PHP isn’t as easy as working with JSON

<?php
$list = array(
"eggs",
"bread",
"milk",
"bananas",
"bacon",
"cheese"
);
$xml = new SimpleXMLElement("<list />");
foreach($list as $item) {
$xml->addChild("item", $item);
}
// for nice output
$dom = dom_import_simplexml($xml)->ownerDocument;
$dom->formatOutput = true;
echo $dom->saveXML();


The starting point is the array that will be our list,
then a SimpleXMLElementobject is
instantiated with a root tag that forms the basis
 for the document. In XML, everything
has to be in a tag so an  <item>tag has been
 introduced in order to contain each list item.
The final block only makes the output prettier,
 which isn’t usually important because
XML is for machines, not for humans.
To get the XML to convert from a  SimpleXM
LElementobject, call the asXML()method
 on that object, which returns a string. The
string, however is all on one line!
The previous example instead converted
 from SimpleXMLElementto DOMElement, and
then grabbed the DOMDocumentfrom that.
 Set the formatOutputto true, so when a call
is made to DOMDocument::saveXML
  to ask it to return the XML as a string), the re‐
sulting output will be nicely formatted.

XML’s abilities to represent attributes, children,
 and character data all provide a more
powerful and descriptive way to represent data
than, for example, JSON. These same
features make XML a great way to represent very
 detailed information, including datatype information,
 so it’s a great choice when those details really do matter.
 It can include

SimpleXML does have some limitations, but it
is recommended for most applications.

2. DOM is handy when a project encounters some

Rewriting Keyword-Rich URLs

rules for your .htaccess file

Modify the .htaccessfile in your seophpfolder like this:
RewriteEngine On
# Rewrite numeric URLs
RewriteRule ^Products/C([0-9]*)/P([0-9]*)\.html$ i
/product.php?category_id=$1&product_id=$2 [L]

# Rewrite keyword-rich URLs
RewriteRule ^Products/.*-C([0-9]+)/.*-P([0-9]+)\.html$ i
/product.php?category_id=$1&product_id=$2 [L]

Load http://test.example.com/Products/Tools-C5/Super-Drill-P9.html

The new rule matches URLs that start with the string Products/, then contain a number of zero or more
characters (.*) followed by –C. This is expressed by ^Products/.*-C. The next characters must be one
or more digits, which as a whole are saved to the $1variable, because the expression is written between
parentheses — ([0-9]+). This first variable in the URL, $1, is the category ID

After the category ID, the URL must contain a slash, then zero or more characters (.*), then -P, as expressed
by /.*-P. Afterward, another captured group follows, to extract the ID of the product, ([0-9]+), which
becomes the $2variable. The final bit of the regular expression, \.html$, specifies the URL needs to end
in .html.
The two extracted values, $1and $2, are used to create the new URL, /product.php?category_id=
$1&product_id=$2. Figure 3-13 describes the process visually.

Top codeigniter interview question and answers

codeigniter interview question

 What is codeigniter?
Codeigniter is open source , web application framework.Its is for building websites using php.Codeigniter is loosely based on MVC pattern.Most simple framework in php , which is you will easily learn.Its mostly known for its speed as compare to other frameworks in php.
Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries.

 When and who developed codeigniter?
The first public version of CodeIgniter was released on February 28, 2006.

 What are the features of codeigniter?
 Codeigniter is free to use,its an open source framework.
 Its light weight.The core system requires only a few very small libraries.Not like other frameworks that require heavy file libraries.
Why codeigniter?
 CodeIgniter is Fast.Its faster than any other framework in php.
 The URLs generated by CodeIgniter are clean and search-engine friendly.You will change any url to what ever you want from files.
 CodeIgniter is Extensible.The system can be easily extended through the use of your own libraries, helpers, or through class extensions or system hooks.

What is MVC
 CodeIgniter Uses MVC(Model View Controller) which allows great separation between logic and presentation.

 CodeIgniter requires nearly zero configuration,does not require you to use the command line,not forced to learn a templating language.

 Full Featured database classes with support for several platforms,Security and XSS Filtering,Error Logging.
 Explain Codeigniter File Structure.

When you download Codeigniter you will see the following folder structure :-

    application
        cache
        Config
        Controllers
        core
        errors
        helpers
        hooks
        language
        libraries
        logs
        models
        thirdparty
        views
    system
        core
        database
        fonts
        helpers
        language
        libraries
 Explain MVC in Codeigniter.
  Controller:- The Controller serves as an intermediary between the Model
, the View. controller mediates input, converting it to
commands for the model or view.

Model:-The Model represents your data structures. Typically your model classes will contain functions that help you retrieve, insert,
and update information in your database.The model consists of application data and business rules.

View:-The View is the information that is being presented to a user. A View will normally be a web page.A view can be any output representation of data.

What are the hooks in codeigniter?
CodeIgniter’s Hooks feature provides a means to tap into and modify the inner workings of the framework without hacking the core files.How ever you like to cause some action to take place at a particular stage in the execution process.
he hooks feature can be globally enabled/disabled by setting the following item in the application/config/config.php file:
$config['enable_hooks'] = TRUE;

Hooks are defined in application/config/hooks.php file.For example
    $hook['pre_controller'] = array(
     'class'    =&gt; 'MyClass',
     'function' =&gt; 'Myfunction',
     'filename' =&gt; 'Myclass.php',
     'filepath' =&gt; 'hooks',
     'params'   =&gt; array('test', 'test1', 'webs')
     );

What are the helpers in codeigniter?
Helpers, as the name suggests, help you with tasks. Each helper file is simply a collection of functions in a particular category.There are URL Helpers, that assist in creating links, there are Form Helpers that help you create form elements, Text Helpers perform various text formatting routines, Cookie Helpers set and read cookies, File Helpers help you deal with files, etc.

Loading a helper file is quite simple using the following function:
    $this->load->helper('name');

How you will use or add codeigniter libraries?
All of the available libraries are located in your system/libraries folder. In most cases, to use one of these classes involves initializing it within a controller using the following initialization function:-
    $this->load->library('class name');

PHP-final METHODS-override a final method

However, there are times where you might want to make
sure that a method cannot be re-implemented in its derived
 classes. For this purpose, PHP supports the Java-like final
access modifier for methods that declares the method as
the final version, which can’t be overridden.
The following example is not a valid PHP script because it is trying to
override a finalmethod:
class MyBaseClass {
final function idGenerator()
{
return $this->id++;
}
protected $id = 0;
}
class MyConcreteClass extends MyBaseClass {
function idGenerator()
{
return $this->id += 2;
}
}

INHERITANCE OF INTERFACES
Interfaces may inherit from other interfaces. The syntax is
similar to that of classes, but allows multiple inheritance:

interface I1 extends I2, I3, ... {
...
}
Similar to when classes implement interfaces, an interface can only
extend other interfaces if they don’t clash with each other which means that
you receive an error if I2defines methods or constants already defined by I1.

Aarray And multiple array values

array[key_element1] => array(1, 2,3);
array[key_element2] => array(4, 5, 6);

 associative arrays
array[key1] => array(key => value1, key => value2, key => value3);
array[key2] => array(key => value4, key => value5, key => value6);

Basically parsing the $values array and pulling the relevant value out.
 Unsetting the array as we go to leave only the values which were not
 sorted. The remaining items in the array will be merged after the loop.
 with array_merge.

PHP array

$values = array('value1', 'value2', 'value3', 'value4', 'value5', 'value6');
$keys = array(0, 2, 1, 5);

foreach ($keys AS $key) {
    $tempOutput[] = ($values[$key])?$values[$key]:'';
    unset($values[$key]);
}

$output = array_merge($tempOutput, $values);


Make new array be joining 2 arrays
shuffle($countries);
$n = count($countries); $i = 0;
$jumble = array();
foreach ($names as $name) {
    if (!isset($jumble[$name])) $jumble[$name] = array();
    $jumble[$name][] = $countries[$i++ % $n];

PHP Session expire-minutes inactivity

session_cache_limiter('public');
session_cache_expire(15);
//should expire after 15  minutes inactivity

asy way to handle this, is to set a variable to $_SESSION
 every time the user visits the page after a successful login.
You can check that variable every time the page loads, and then
 you will know the last time they requested a page from the site,
 and can compare it to the current time to determine what to do from there.

session.gc_maxlifetime
session.gc_maxlifetime specifies the number of seconds after which data
 will be seen as 'garbage' and cleaned up. Garbage collection occurs
 during session start.

Furthermore, when using PHP's default session.save_handler files,
 the session data is stored in files in a path specified in session.save_path.
 With that session handler, the age of the session data is calculated on the
 file's last modification date and not the last access date.

if (isset($_SESSION['LAST_ACTIVITY']) &&
 (time() - $_SESSION['LAST_ACTIVITY'] > 1800)) {
    // last request was more than 30 minutes ago
    session_unset();     // unset $_SESSION variable for the run-time
    session_destroy();   // destroy session data in storage
}
$_SESSION['LAST_ACTIVITY'] = time(); // update last activity time stamp

          OR

if (!isset($_SESSION['CREATED'])) {
    $_SESSION['CREATED'] = time();
} else if (time() - $_SESSION['CREATED'] > 1800) {
    // session started more than 30 minutes ago
    session_regenerate_id(true);  
// change session ID for the current session and invalidate old session ID
    $_SESSION['CREATED'] = time();  // update creation time
}

Note that session.gc_maxlifetime should be at least equal to the
 lifetime of this custom expiration handler 1800 in this example.

PHP INTERFACES

Class inheritanceenables you to describe a parent-child relationship
between classes. For example, you might have a base class
 Shapefrom which both Squareand Circlederive. However,
 you might often want to add additional “interfaces” to classes,
 basically meaning additional
 contracts to which
the class must adhere. This is achieved in C++ by using multiple
 inheritance and deriving from two classes. PHP chose interfaces
 as an alternative to multiple inheritance, which allows you to specify
 additional contracts a class must follow. An interface is declared
similar to a class but only includes function prototypes without
implementation and constants. Any class that “implements”
 this interface automatically has the interface’s constants defined and,
as the implementing class, needs to supply the function definitions for the
interface’s function prototypes that are all abstractmethods unless you
declare the implementing class as abstract.

abstract class Shape {
function setCenter($x, $y) {
$this->x = $x;
$this->y = $y;
}
abstract function draw();

protected $x, $y;
}
class Square extends Shape {
function draw()
{
// Here goes the code which draws the Square
...
}
}
class Circle extends Shape {
function draw()
{
// Here goes the code which draws the Circle
...
}
}
You can see that the draw()abstract method does not
 contain any code.

To implement an interface, use the following syntax:
class A implements B, C, ... {
...
}

Classes that implement an interface have an instance of a relationship
 with the interface; for example, if class Aimplements interface
 myInterface, the following results in '$obj is-A myInterface'printing:

$obj = new A();
if ($obj instanceof myInterface) {
print '$obj is-A myInterface';
}

parent AND self PHP oops

 parent  AND self PHP oops

self::refers to the current class and it is usually used to access
static members, methods, and constants. parent::refers to the
 parent class and it is most often used when wanting to call the
 parent constructor or methods. It may also be used to access
members and constants. You should use parent::as
opposed to the parent’s class name because it makes it easier
 to change your class hierarchy because you are not hard-coding
 the parent’s class name.

The following example makes use of both parent::and self::for
 accessing the Childand Ancestorclasses:

class Ancestor {
const NAME = "Ancestor";
function __construct()
{
print "In " . self::NAME . " constructor\n";
}
}
class Child extends Ancestor {
const NAME = "Child";
function __construct()
{
parent::__construct();
print "In " . self::NAME . " constructor\n";
}
}
$obj = new Child();

The previous example outputs
In Ancestor constructor
In Child constructor
Make sure you use these two class names whenever possible.

Static Methods-PHP

 PHP supports declaring methods as static.
Whatthis means is that your static methods are part of the
 class and are not bound to any specific object instance and
 its properties. Therefore, $this isn’t accessible in these methods,
 but the class itself is by using selfto access it. Because
static methods aren’t bound to any specific object, you can
 call them without creating an object instance by using the
class_name::method()syntax. You may also call them from an
 object instance using $this->method(), but $thiswon’t
be defined in the called method. For clarity, you should use self::method()
instead of $this->method().

class PrettyPrinter {
static function printHelloWorld()
{
print "Hello, World";
self::printNewline();
}
static function printNewline()
{
print "\n";
}
}
PrettyPrinter::printHelloWorld();

The example prints the string "Hello, World"followed by a newline.
Although it is a useless example, you can see that printHelloWorld()can be
called on the class without creating an object instance using the class name,
and the static method itself can call another static method of the
class printNewline()using the self::notation. You may call a parent’s
 static method by using the parent::notation.

Static Properties

As you know by now, classes can declare properties. Each instance of the
class,object has its own copy of these properties. However, a class can
also contain static properties. Unlike regular properties, these belong to
the class itself and not to any instance of it.

class propertiesas opposed to object or instance properties. You can also
think of static properties as global variables that sit inside a class but are
accessible from anywhere via the class.
Static properties are defined by using the static keyword:
class MyClass {
static $myStaticVariable;
static $myInitializedStaticVariable = 0;
}
To access static properties, you have to qualify the property name with
the class it sits in

MyClass::$myInitializedStaticVariable++;
print MyClass::$myInitializedStaticVariable;

What is array

Arrays
An arrayin PHP is a collection of key/value pairs.
 This means that it maps keys or indexes to values.
Array indexescan be either integers or strings
whereas values can be of any type.
Arrays in PHP are implemented using hash tables, which
 means that accessing a value has an average complexity.

array()construct Arrays can be declared using the array()language
 construct, which generally takes the following form elements inside
square brackets, [], are optional:

array([key =>] value, [key =>] value, ...)

The key is optional, and when it’s not specified, the key is
 automatically assigned one more than the largest previous
 integer key starting with 0. You can intermix the use with
 and without the key even within the same declaration.
The value itself can be of any PHP type, including an array.
 Arrays containing arrays give a similar result as multi-dimensional
 arrays in other languages.

Accessing Array Elements Array elements can be accessed by using
the $arr[key]notation, where keyis either an integer or string expression.
When using a constant string for key,make sure you don’t forget the single or
double quotes, such as $arr["key"]. This notation can be used for both reading
array elements and modifying or creating new elements.

$arr1 = array(1, 2, 3);
$arr2[0] = 1;
$arr2[1] = 2;
$arr2[2] = 3;
print_r($arr1);
print_r($arr2);

The print_r()function has not been covered yet in this book, but when it
is passed an array, it prints out the array’s contents in a readable way. You can
use this function when debugging your scripts.

Array
(
[0] => 1
[1] => 2
[2] => 3
)
Array
(
[0] => 1
[1] => 2
[2] => 3
)
So, you can see that you can use both the array()construct
 and the $arr[key] notation to create arrays.
Usually, array()is used to declare arrays
whose elements are known at compile-time, and
 the $arr[key]notation is used when the elements
 are only computed at runtime.
PHP also supports a special notation, $arr[], where the key is
 not specified. When creating new array offsets using
 this notation , the key is automatically assigned as one
 more than the largest previous integer key.

Therefore, the previous example can be rewritten as follows:
$arr1 = array(1, 2, 3);
$arr2[] = 1;
$arr2[] = 2;
$arr2[] = 3;

$arr1 = array("name" => "John", "age" => 28);
$arr2["name"] = "John";
$arr2["age"] = 28;
if ($arr1 == $arr2) {
print '$arr1 and $arr2 are the same' . "\n";
}

Reading array values You can use the
 $arr[key]notation to read array values.
The next few examples build on top of the previous example:
print $arr2["name"];
if ($arr2["age"] < 35) {
print " is quite young\n";
}

strtotime php-current time zone

strtotime()parsing is always done with the current time zone,
unless a different time zone is specified in the string that is parsed:
<?php
echo date("H:i T\n", strtotime("09:22")); // shows 09:22 CET
echo date("H:i T\n\n", strtotime("09:22 GMT")); // shows 10:22 CET
echo gmdate("H:i T\n", strtotime("09:22")); // shows 08:22 GMT
echo gmdate("H:i T\n", strtotime("09:22 GMT")); // shows 09:22 GMT
?>

Using the strtotime()function is easy. It accepts two parameters: the
string to parse to a timestamp and an optional timestamp. If the
 timestamp is included, the time is converted relative to the
 timestamp; if it’s not included,the current time is used. The relative
 calculations are only written with yesterday, tomorrow, and the 1
 year 2 days ago format strings.
