Renaming Files and Directories
There are a few useful file and directory functions built-in to
PHP which I'll cover in brief here. They include renaming and deleting files as
well as listing files located in a directory. I'll review the syntax for some of
them first and then demonstrate how they function within the context of a very
useful PHP script.
First, there is the rename() function, which works as
you would expect it to:
rename ("filenameold", "filnamenew");
It can be used on either files or directories.
Renames a file from the old filename to the new filename. The
user that PHP runs as must have sufficient permissions to rename the file.
Returns TRUE on success;
FALSE on failure
<?php
$fileold = "oldfile";
$filenew = "newfile";
if(!rename($fileold, $filenew))
{
echo ("Rename process failed");
}
?>
