Magic Methods and Constants
Magicmethods are specially named methods that
can be defi nedin any class and are executed via builtin PHP functionality. Magic methods always begin with a double underscore. In fact, the magic methods __destruct() and __construct() have already been used several times.
It is often useful to determine where in the code output originates.
This is the purpose of all of the magic constants and is particularlyuseful when writing custom logging functions. The seven magic constants are as follows:
__CLASS__ equates to the class in which the constant is referenced.
As noted earlier, this variable is always equal to the class in which it is defi ned, which is not always the class that was instantiated. For example, __CLASS__ as defi ned inside Node always returns Node even if the method is part of an object that was instantiated as a descendant class. In addition to debugging, the class constant is also useful for static callback functions.
__FILE__ is always equal to the file name where the constant is referenced.
__LINE__ is used in conjunction with __FILE__ in order to output a location in code.

Php HTTP BasicsWhen a web browser requests a web page, it sends an HTTP requestmessage to a web server. The request message always includes some header information, and it sometimes also includes a body. The web server responds with a reply message, which always includes header information and usually contains a body. The first line of an HTTP request looks like this: GET /index.html HTTP/1.1 This line specifies an HTTP command, called a method , followed by the address of a document and the version of the HTTP protocol being used. In this case, the request is using the GET method to ask for the index.html document using HTTP 1.1. After this initial line, the request can contain optional header information that gives the server additional data about the request. For example: User-Agent: Mozilla/5.0 Windows 2000; U Opera 6.0 [en] Accept: image/gif, image/jpeg, text/*, */* The User-Agent header provides information about the web browser, while the Accept headerspecifies the MIME types that the browser accepts. After any headers, the request contains a blank line, to indicate the end of the header section. The request can also contain additional data, if that is appropriate for the method being used . If the request doesn't contain any data, it ends with a blank line. The web server receives the request, processes it, and sends a response. The first line of an HTTP response looks like this: HTTP/1.1 200 OK This line specifies the protocol version, a status code, and a description of that code. In this case, the status code is "200", meaning that the request was successful hence the description OK. After the status line, the response contains headers that give the client additional information about the response. For example: Date: Sat, 26 Jan 2002 20:25:12 GMT Server: Apache 1.3.22 Unix mod_perl/1.26 PHP/4.1.0 Content-Type: text/html Content-Length: 141 The Server header provides information about the web server software, while the Content-Type header specifies the MIME type of the data included in the response. After the headers, the response contains a blank line, followed by the requested data, if the request was successful. |

HTTP is the standard that allows documents to be communicated and shared over the Web. From a network perspective, HTTP is an application-layer protocol that is built on top of TCP/IP. Using our courier analogy from the previous section, HTTP is a kind of cover letter—like a fax cover sheet—that is stored in the envelope and tells the receiver what language the document is in, instructions on how to read the letter, and how to reply. Since the original version, HTTP/0.9, there have only been two revisions of the HTTP standard. HTTP/1.0 was released as RFC-1945[A] in May 1996 and HTTP/1.1 as RFC-2616 in June 1999. HTTP is simple: a client—most conspicuously a web browser—sends a request for some resource to a HTTP server, and the server sends back a response. The HTTP response carries the resource—the HTML document or image or whatever—as its payload back to the client. A simulated HTTP request using telnet % telnet www.w3.org 80 Trying 18.29.1.35...

Creating a Simple Php Functions
Creating a Simple Php Functions
As you program, you'll discover that there are certain sections of code you frequently use, either within a single script or in several. Placing these routines into a self-defined function can save you time and make your programming easier, especially as your Web sites become larger. Once you create a function, the actions of that function take place each time the function is called, just as print() will send text to the browser with each use. The syntax to create a user-defined function is: function FunctionName () { statement(s); }You can use roughly the same naming conventions for the function name as you do for variables, just without the initial dollar sign. The most important rule is to remain consistent. Second to that is the suggestion of creating meaningful function names, just as you ought to write representative variable names CreateHeader would be a better function name than Function1.
Remember not to use spaces, though, as that would constitute two separate words for the function name, which will result in error messages the underscore is a logical replacement for the space, for example Create_Header is a valid function name.
Any valid PHP code can go within the statements area of the function, including calls to other functions. There is also no limit to the number of statements a function has, but make sure each statement ends with a semi-colon.

Adding CSS style in php script
<?php
echo '<span style="font-size:10px">'; // add styles as style attribute
echo 'test';
echo '</span> ';
echo '<p style="font-size:20px">';
echo $title = $_POST['text'];
echo "</p>";
?>
In PHP, all variable names begin with a dollar sign ($). The $ is followed by an
alphabetic character or an underscore, and optionally followed by a sequence of
alphanumeric characters and underscores. There is no limit on the length of a
variable name. Variable names in PHP are case-sensitive. Here are some examples:
$k
$cot
$Sar_name
$_MPS
In PHP, unlike in many other languages, you do not have to explicitly declare variables.
PHP automatically declares a variable the first time a value is assigned to it.
PHP variables are untyped; you can assign a value of any type to a variable.
PHP uses a symbol table to store the list of variable names and their values.
There are two kinds of symbol tables in PHP: the global symbol table, which stores
the list of global variables, and the function-local symbol table, which stores the
set of variables available inside each function.
Dynamic Variables
Sometimes it is useful to set and use variables dynamically. Normally, you assign a variable like this:
$var = "derro";
Now let's say you want a variable whose name is the value of the $var variable. You can do that like this:
$$var = "Jinna";
PHP parses $$var by first dereferencing the innermost variable, meaning that
$var becomes "derro". The expression that's left is $"hello", which is just $derro.
In other words, we have just created a new variable named hello and assigned it
the value "Jinna". You can nest dynamic variables to an infinite level in PHP,
although once you get beyond two levels, it can be very confusing for someone who
is trying to read your code.
echo '<span style="font-size:10px">'; // add styles as style attribute

Php-Associative Arrays
Arrays are another basic structure in programming languages. Arrays provide means for
storing a fixed set (or collection) of the same datatype in a convenient way, making
each element of your set indexable by using a unique key.
In the typical "conventional" programming languages, arrays are handled like this:
int my_int_array[786]; // allocate 786 integers in this array
This C code snippet declares an array called my_integer_array, containing 256 integers.
You can address each of these integers by indexing the array with an ordinal value, for this array in a range from 0 to 255. (C starts counting from 0; the given number in the array definition specifies the number of integers you want to have available.) Indexing looks like this:
int my_integer = my_integer_array[4];
This retrieves the fifth element remember, C starts counting from 0 from the array
and stores it in my_integer.
Arrays for coding
Contents of Arrays can be stretched,
Arrays easily help group related information such as server login detailstogether
Arrays help write cleaner code.
Arrays are special variableswith the capacityto store multi values.
Arrays are flexibilityand can be easily stretchedto accommodate more values
Numeric arraysuse numbers for the array keys
Associative arraysuse descriptive namesfor array keys
Multidimensionalarrays contain other arrays insidethem.
The countfunction is used to get the numberof itemsthat have been stored in an array
The is_arrayfunction is used to determinewhether a variableis a valid array or not.
Other array functions include sort, ksort, assort etc.
Due to the nature of compiled languages, you were always bound to the previous
definition of your variables. If you suddenly needed more than 256 integers in the array above, this was impossible. Of course, you could have defined this variable as a pointer to an integer array and allocated 257 elements for it—but what if you suddenly needed another element? You'd have to allocate new space, copy the old array contents, and free up the old, unused space.
PHP takes a different approach. Because PHP knows no typical variable declarations only type definitions
), new variables are allocated on the fly. Whenever you create a new variable by introducing its
name into the namespace, you simply create storage space bound to this name—nothing more. The kind of data residing in this space is not restricted to a certain variable type. It can be reinterpreted on the fly, and of course resized, reallocated, whatever.
Take a look at this:
$my_var = 1;
$my_var = "Used to be an integer";
$my_var = array("Oh well, I like arrays better");
The first line creates a new variable $my_var.
PHP will find that an integer is going to be assigned to it; thus it sets the initial
type of $my_var to integer. The second line, however, overwrites the contents of $my_var
with a string. Using one of the conventional programming languages, this would have
resulted in an error at compile time, or at least an exception during runtime.
But PHP dynamically changes the type of $my_var to String and reallocates the variable
so that enough storage space for the string is available. The third line then changes
the type of $my_var once more by creating an array out of it. PHP handles all cases
transparently without complaining. (We know that other languages out there exist
without strict variable types.
Note: PHP 3.0 doesn't have proper garbage collection. When reallocating a variable,
memory that's already allocated is not always being reused. In long-term scripts or
scripts doing heavy processing.
Because formal variable declarations are not needed in PHP variable usage is completely
dynamic. A special case in PHP's dynamic variable handling is arrays. You probably
know the common array type, the indexed array. Indexed arrays are arrays that are
indexed by ordinal numbers. These ordinal indices typically range from 0 to n, n
being the highest possible index. Languages such as Pascal allow indexing with
different ranges such as from 3 to 18; however, these ranges are transformed back
to 0-based indexes at runtime. The key feature of these ordinally indexed arrays is
that you can compute another index from any given base index. For example, suppose
you want to read out three consecutive array elements, starting from index 2:
$base_index = 2;
for($i = $base_index; $i < $base_index + 3; $i++)
print("Element $i is $my_array[$i]<br>");
In every iteration of the for() statement, this little snippet computes the next
index into the array by incrementing $i.
Associative arrays don't have this feature. The special thing about associative arrays
is that they can be indexed with non-ordinal keys, such as strings, for example.
Every string used as an index has a value associated to it, thus the name associative arrays.
As you can imagine, giving a string as base index doesn't allow guessing the next valid index
in the array. Thus, associative arrays can't be used to order data elements in an ordinal way.
You have to know the array keys to retrieve their associated values.
Apart from that, the functions list() and each(), discussed earlier,
can be used to traverse associative arrays.
Indexed arrays are just a special form of associative arrays in PHP. Doing an unset() on
one of the elements in an indexed array will leave all other elements and their ordering
intact, but produce a nonconsecutive array. See the earlier descriptions of
list() and each() for details.
Multidimensional Arrays
As the name suggests, multidimensional arrays are arrays with more than just one dimension.
One-dimensional (or single-dimensional) arrays are the form in which arrays are mostly seen:
$my_array[0] = 1;
$my_array[1] = 777;
$my_array[2] = 45;
To index this type of array, you only need one index, which limits the number of possible
values to the range of this index. But it's often very useful to create multidimensional
arrays when handling complex datasets. Typical examples include bitmaps and screen buffers.
When you look at your monitor, you see at least these days a two-dimensional projection of
your desktop. The windows, bitmaps, command lines, cursors, pointers—everything is 2D.
To represent this data in a convenient way, you could of course serialize everything
into arrays with a single dimension—but the more appropriate method is to use arrays
with dimensions equal to those of the input data. For example, in order to store a bitmap
a set of pixels for a mouse pointer, you just add another index to your array:
// clear mouse bitmap
for($x = 0; $x < MOUSE_X_SIZE; $x++)
for($y = 0; $y < MOUSE_Y_SIZE; $y++)
$mouse_bitmap[$x][$y] = 0;
storing a fixed set (or collection) of the same datatype in a convenient way, making
each element of your set indexable by using a unique key.
In the typical "conventional" programming languages, arrays are handled like this:
int my_int_array[786]; // allocate 786 integers in this array
This C code snippet declares an array called my_integer_array, containing 256 integers.
You can address each of these integers by indexing the array with an ordinal value, for this array in a range from 0 to 255. (C starts counting from 0; the given number in the array definition specifies the number of integers you want to have available.) Indexing looks like this:
int my_integer = my_integer_array[4];
This retrieves the fifth element remember, C starts counting from 0 from the array
and stores it in my_integer.

index into the array by incrementing $i.
Associative arrays don't have this feature. The special thing about associative arrays

Every string used as an index has a value associated to it, thus the name associative arrays.

To index this type of array, you only need one index, which limits the number of possible
values to the range of this index. But it's often very useful to create multidimensional
arrays when handling complex datasets. Typical examples include bitmaps and screen buffers.
When you look at your monitor, you see at least these days a two-dimensional projection of
your desktop. The windows, bitmaps, command lines, cursors, pointers—everything is 2D.
To represent this data in a convenient way, you could of course serialize everything
into arrays with a single dimension—but the more appropriate method is to use arrays
with dimensions equal to those of the input data. For example, in order to store a bitmap
a set of pixels for a mouse pointer, you just add another index to your array:
// clear mouse bitmap
for($x = 0; $x < MOUSE_X_SIZE; $x++)
for($y = 0; $y < MOUSE_Y_SIZE; $y++)
$mouse_bitmap[$x][$y] = 0;
LOAD DATA INFILE statement MySQL
LOAD DATA INFILE provides an alternative to INSERT for adding new
records to a table. With INSERT, you specify data values directly in the INSERT statement.
LOAD DATA INFILE reads the values from a separate datafile.
The simplest form of the LOAD DATA INFILE statement specifies only the name of the datafile
and the table into which to load the file:
LOAD DATA INFILE 'file_name' INTO TABLE table_name;
The filename is given as a string and must be quoted. MySQL assumes, unless told otherwise,
that the file is located on the server host, that it has the default file format
tab-delimited and newline-terminated lines, and that each input line contains a value
for each column in the table. However, LOAD DATA INFILE has clauses that give you control
over each of those aspects of data-loading operations and more:
Which table to load
The name and location of the datafile
Which columns to load
The format of the datafile
How to handle duplicate records
Whether to ignore lines at the beginning of the datafile
The syntax for LOAD DATA INFILE is as follows, where optional parts of
the statement are indicated by square brackets:
LOAD DATA [LOCAL] INFILE 'file_name'
[IGNORE | REPLACE]
INTO TABLE table_name
format_specifiers
[IGNORE n LINES]
[(column_list)]
The following sections explain how the various parts of the statement work.
Specifying the Datafile Location
LOAD DATA INFILE can read datafiles that are located on the server host
or on the client host:
By default, MySQL assumes that the file is located on the server host.
The MySQL server reads the file directly.
If the statement begins with LOAD DATA LOCAL INFILE rather than with LOAD DATA INFILE,
the file is read from the client host on which the statement is issued. In other words
, LOCAL means local to the client host from which the statement is issued. In this case,
the client program reads the datafile and sends its contents over the network to the server.
The rules for interpreting the filename are somewhat different for the server
host and the client host.
Specifying the Location of Files on the Server Host
Without LOCAL in the LOAD DATA INFILE statement, MySQL looks for the datafile
located on the server host and interprets the pathname as follows:
If you refer to the file by its full pathname, the server looks for the file
in that exact location.
If you specify a relative name with a single component, the server looks for
the file in the database directory for the default database. (This isn't necessarily
the database that contains the table into which you're loading the file.)
If you specify a relative pathname with more than one component, the server
interprets the name relative to its data directory.
Suppose that the server's data directory is /var/mysql/data, the database directory
for the test database is /var/mysql/data/test, and the file data.txt is located in
that database directory. Using the filename interpretation rules just given, it's
possible to refer to the data.txt file three different ways in a LOAD DATA INFILE statement:
You can refer to the file by its full pathname:
LOAD DATA INFILE '/var/mysql/data/test/data.txt' INTO TABLE t;
If test is the default database, you can refer to a file in the database directory
using just the final component of its pathname:
LOAD DATA INFILE 'data.txt' INTO TABLE t;
You can refer to any file in or under the server's data directory by its
pathname relative to that directory:
LOAD DATA INFILE './test/data.txt' INTO TABLE t;
Specifying the Location of Files on the Client Host
If you use LOCAL to read a datafile located on the client host, pathname
interpretation is simpler:
If you refer to the file by its full pathname, the client program looks for
the file in that exact location.
If you specify a relative pathname, the client program looks for the file relative
to its current directory. Normally, this is the directory in which you invoked the program.
Suppose that there's a datafile named data.txt located in the /var/tmp directory
on the client host and you invoke the mysql program while located in that directory.
You can load the file into a table t using either of these two statements:
LOAD DATA LOCAL INFILE '/var/tmp/data.txt' INTO TABLE t;
LOAD DATA LOCAL INFILE 'data.txt' INTO TABLE t;
The first statement names the file using its full pathname. The second names the file relative
to the current directory. If you invoke the mysql program in the /var directory instead, you
can still load the file using the same full pathname. However, the relative pathname to the
file is different than when running the program in the /var/tmp directory:
LOAD DATA LOCAL INFILE 'tmp/data.txt' INTO TABLE t;
Specifying Filenames on Windows
On Windows, the pathname separator character is \, but MySQL treats the backslash as
the escape character in strings. To deal with this issue, write separators in Windows
pathnames either as / or as \\. To load a file named C:\mydata\data.txt, specify the filename
as shown in either of the following statements:
LOAD DATA INFILE 'C:/mydata/data.txt' INTO TABLE t;
LOAD DATA INFILE 'C:\\mydata\\data.txt' INTO TABLE t;
Loading Specific Table Columns
By default, LOAD DATA INFILE assumes that data values in input lines are present
in the same order as the columns in the table. If the datafile contains more columns
than the table, MySQL ignores the excess data values. If the datafile contains too
few columns, each missing column is set to its default value in the table. This is the same
way MySQL handles columns that aren't named in an INSERT statement.
If input lines don't contain values for every table column, or the data values are not in
the same order as table columns, you can add a comma-separated list of column names within
parentheses at the end of the LOAD DATA INFILE statement. This tells MySQL how columns in
the table correspond to successive columns in the datafile.
records to a table. With INSERT, you specify data values directly in the INSERT statement.
LOAD DATA INFILE reads the values from a separate datafile.
The simplest form of the LOAD DATA INFILE statement specifies only the name of the datafile
and the table into which to load the file:
LOAD DATA INFILE 'file_name' INTO TABLE table_name;

PHP identical operator ===
Variable types are also important in comparison.When you compare two variables
with the identical operator (===), like this, the active types for the zvals are compared,
and if they are different, the comparison fails outright:
$a = 0;
$b = ‘0’;
echo ($a === $b)?”Match”:”Doesn’t Match”;
For that reason, this example fails.
With the is equal operator (==), the comparison that is performed is based on the
active types of the operands. If the operands are strings or nulls, they are compared as
strings, if either is a Boolean, they are converted to Boolean values and compared, and
otherwise they are converted to numbers and compared.Although this results in the ==
operator being symmetrical (for example, if $a == $bis the same as $b == $a), it actually
is not transitive.The following example of this was kindly provided by Dan Cowgill:
$a = “0”;
$b = 0;
$c = “”;
echo ($a == $b)?”True”:”False”; // True
echo ($b == $c)?”True”:”False”; // True
echo ($a == $c)?”True”:”False”; // False
Although transitivity may seem like a basic feature of an operator algebra, understanding
how ==works makes it clear why transitivity does not hold. Here are some examples:
n “0” == 0because both variables end up being converted to integers and compared.
n $b == $cbecause both $band$care converted to integers and compared.
n However,$a != $cbecause both $aand$care strings, and when they are compared as strings,
they are decidedly different.
In his commentary on this example, Dan compared this to the ==andeqoperators in
Perl, which are both transitive.They are both transitive, though, because they are both
typed comparison.==in Perl coerces both operands into numbers before performing the
comparison, whereas eqcoerces both operands into strings.The PHP ==is not a typed
comparator, though, and it coerces variables only if they are not of the same active type.
Thus the lack of transitivity.

The $_REQUEST Variable-php
PHP is a lot more than a way to work with text. You’ve been working with strings
non-stop, but there are a lot more types of information you’ll need to work with
in your PHP scripts. As you might expect, there are all kinds of ways to work with
numbers, and you’ll work with numbers quite a bit before long.
But there’s another really important type of information you need to understand;
in fact, you’ve already been working with this type, as much as you’ve worked with
text. This mystery type is an array: a sort of container that actually holds other
values within it.
Working with $_REQUESTas an Array This special
variable PHP gave you with all the information from a web form, called
$_REQUEST, is also an array. And when you’ve written code like
$_REQUEST['first_name'],
you’ve just been grabbing a particular piece of information out of that array.
foreach($_REQUEST as $value)
{
echo "<p>" . $value . "</p>";
}
Everything between the { }runs once for each time through the loop. So that means
that for every item in $_REQUEST, this line is going to run one time:
echo "<p>" . $value . "</p>";
This line shouldn’t be any big deal to you at all: it just prints out $valuewith some
HTML formatting. But since each time through this loop, $valuehas a different value
from $_REQUEST, it’s a quick way to print out every value in $_REQUEST.
<div id="content">
<p>Here's a record of everything in the $_REQUEST array:</p>
<?php
foreach($_REQUEST as $key => $value) {
echo "<p>For " . $key . ", the value is '" . $value . "'.</p>";
}
?>
</div>
This time, you’re telling foreachto get both the key, as $key, and the value, as $value.
That special =>sign tells PHP you want the $keyand then the $valueattached to
the key. In other words, you’re grabbing a label and the folder that label is attached
to, which is just what you want.

Displaying Browser Specific-php
However, having seen some of the possible values of HTTP_USER_AGENT in the last chapter,
you can imagine that there are hundreds of slightly different values. So it's time to learn
some basic pattern matching.
You'll use the preg_match() function to perform this task. This function needs two arguments:
what you're looking for, and where you're looking:
preg_match("/[what you're looking for]/", "[where you're looking]");
This function will return a value of true or false, which you can use in an if…else block
to do whatever you want. The goal of the first script is to determine if a Web browser is
Microsoft Internet Explorer, Netscape, or something else. This can be a little tricky,
but not because of PHP.
Within the value of HTTP_USER_AGENT, Netscape always uses the string Mozilla to identify
itself. Unfortunately, the value of HTTP_USER_AGENT for Microsoft Internet Explorer also
uses Mozilla to show that it's compatible. Luckily, it also uses the string MSIE, so you
can search for that. If the value of HTTP_USER_AGENT doesn't contain either Mozilla or MSIE,
chances are very good that it's not one of those Web browsers.
Open a new file in your text editor and start a PHP block, then use getenv() to place the
value of HTTP_USER_AGENT in a variable called $agent:
<?
$agent = getenv("HTTP_USER_AGENT");
Start an if…else statement to find which of the preg_match() functions is true, starting
with the search for MSIE:
if (preg_match("/MSIE/i", "$agent")) {
$result = "You are using Microsoft Internet Explorer.";
}
Continue the statement, testing for Mozilla:
else if (preg_match("/Mozilla/i", "$agent")) {
$result = "You are using Netscape.";
}
Finish the statement by defining a default:
else {
$result = "You are using $agent";
}

Network Topologies - Basic
In the seemingly never-ending competition to maximize the
amount of data that can be pushed through a piece of wire, numerous network
topologies have been tried and tested. Initially,
companies offered wholesale solutions for customers wanting to
utilize various software packages. The problem was that these solutions
typically required certain network protocols and certain
hardware be in place before anything would work. This was often
referred to as “monolithic” networking because these solutions
were rarely interoperable with other applications or hardware.
After a company committed to a particular type of network, they
were stuck with that network, and it was just too bad if a really
useful application was released for a different network architecture.
Accommodating a brand new application or suite of applications sometimes
required removing the old network and installing another one.
Administrators therefore wanted to make sure they were planning for the
longest term possible. In an effort to sell administrators on the benefits
of a particular networking package,companies developed network
configurations for maximizing network performance.
Performance was typically rated by how well a network architecture
maximized available bandwidth. The strategies and implementation details for
achieving these goals could be broken down into three general configurations.
These evolved into the Bus, Ring, and Star configurations. It is helpful to
understand how each of these developed.
The Bus Configuration
The bus configuration has its roots with coaxial cable in simple
networks where desktop machines are simply connected together
so that they can share information with each other. Traffic, here
defined as voltage applied to the wire by any machine that needs
to communicate.

4 Invaluable Free Apps
MySQL Workbench
MySQL Workbench is an app that I cannot live without. In some ways, it is
slightly trickier to use than phpMyAdmin. However, it’s located on your PC,
and it gives you the power to do backups and repairs on your databases
and enables you to make changes in a slightly different environment from
phpMyAdmin through your browser. Try it; it’s a tool I prefer to use.
You can download MySQL Workbench for Windows, Linux, or Mac OS X at
http://dev.mysql.com/downloads/workbench/
FileZilla
FileZilla is one of the best — if not the best — free File Transfer Protocol (FTP)
clients available. There are other free ones and there are many that you can
pay for, but FileZilla is my go-to FTP client. It’s fast; it’s efficient; it can do
Secure File Transfer Protocol (SFTP, which you really should be using) or basic
FTP; and it lays everything out in a simple, easy-to-use window.
One warning with FileZilla is that it stores your passwords in a non-protected
file, which means virus and malware writers, if they write stuff which gets
onto your computer, could theoretically read that file and get your FTP login
details, including your password. Of course, that means the attack must
specifically look for your password file — and it has to make it past the
virus checker, which I’m sure you have installed on your PC — but it is a
consideration to note, and you should remember to not store your passwords within FileZilla.
You can download it for Windows, Linux, or Mac OS X at http://
filezilla-project.org.
Notepad++
Notepad++ is a wonderful editor for editing any kind of files: text files, PHP
files, HTML files, CSS files. You name it, Notepad++ can read it. One of things I
like most about it is that, with PHP files, it includes color coding to delineate
different types of elements and helps you see where you are in the file and
identify where the code elements you are working on close.
Notepad++ is available for Windows only. You can download it at http://
notepad-plus-plus.org.
PuTTY
PuTTY is a powerful tool that enables you to connect to devices online, using
a system called telnet, providing you have the correct login details. It is very
useful to website owners, especially those with a Virtual Private Server (VPS)
or dedicated server, because it enables you to open a command-line prompt
on your server by logging in via Secure SHell (SSH), so that you can run commands as needed.
PuTTY comes with dire warnings that you must not use it anywhere where
it’s illegal to use. The research I’ve done suggests that it is legal to use it
within the U.S., providing you’re using it for connection to a device that you
own or have the right to connect .
MySQL Workbench is an app that I cannot live without. In some ways, it is
slightly trickier to use than phpMyAdmin. However, it’s located on your PC,
and it gives you the power to do backups and repairs on your databases
and enables you to make changes in a slightly different environment from
phpMyAdmin through your browser. Try it; it’s a tool I prefer to use.
You can download MySQL Workbench for Windows, Linux, or Mac OS X at
http://dev.mysql.com/downloads/workbench/
FileZilla
FileZilla is one of the best — if not the best — free File Transfer Protocol (FTP)
clients available. There are other free ones and there are many that you can
pay for, but FileZilla is my go-to FTP client. It’s fast; it’s efficient; it can do
Secure File Transfer Protocol (SFTP, which you really should be using) or basic
FTP; and it lays everything out in a simple, easy-to-use window.
One warning with FileZilla is that it stores your passwords in a non-protected
file, which means virus and malware writers, if they write stuff which gets
onto your computer, could theoretically read that file and get your FTP login
details, including your password. Of course, that means the attack must
specifically look for your password file — and it has to make it past the
virus checker, which I’m sure you have installed on your PC — but it is a
consideration to note, and you should remember to not store your passwords within FileZilla.
You can download it for Windows, Linux, or Mac OS X at http://
filezilla-project.org.
Notepad++
Notepad++ is a wonderful editor for editing any kind of files: text files, PHP
files, HTML files, CSS files. You name it, Notepad++ can read it. One of things I
like most about it is that, with PHP files, it includes color coding to delineate
different types of elements and helps you see where you are in the file and
identify where the code elements you are working on close.
Notepad++ is available for Windows only. You can download it at http://
notepad-plus-plus.org.
PuTTY
PuTTY is a powerful tool that enables you to connect to devices online, using
a system called telnet, providing you have the correct login details. It is very
useful to website owners, especially those with a Virtual Private Server (VPS)
or dedicated server, because it enables you to open a command-line prompt
on your server by logging in via Secure SHell (SSH), so that you can run commands as needed.
PuTTY comes with dire warnings that you must not use it anywhere where

How to check broken Links
Broken links are links that do not work, either because they have been miscoded or because
the pages they point to don't exist (perhaps it has been moved).It's quite important to a search
engine that none of the links on your site are broken. It shouldn't be that big a problem to go
through your site and check to make sure each link works manually. Doing this will also give you a
chance to review your site systematically, and understand the navigation flow from the viewpoint
of a bot.
Even though you've checked your links manually, you should also use an automated link-checking tool.
Quite a few are available. A good choice is the simple (and free) link checker provided by the
World Wide Web Consortium (W3C) at http://validator.w3.org/checklink. All you need to do is enter
the domain you want checked and watch the results as the links in your site are crawled.
You want as many inbound links as possible, provided these links are not from link farms
or link exchanges. With this caveat about inbound linking from understood, you cannot have
too many inbound links. The more popular (and the higher the ranking) of the sites providing
the inbound links to your site, the better.
Inbound links are considered a shorthand way of determining the value of your web site, because
other sites have decided your site has content worth linking to. An inbound link from a site that
is itself highly valued is worth more than an inbound link from a low-value site,
for obvious reasons.
