PHP strpos()

strpos() is a useful PHP function that will allow you to find the first occurency of a string in another string, a common error is to place the arguments like with the ereg() function :

Description:
int strpos ( string $haystack , mixed $needle [, int $offset ] )


Here is an example:
<?php

$mystring = 'abcdef';
$findme  = 'a';

$pos = strpos($mystring, $findme);

// Please now note the use of === to make the difference between 0 and false

if ($pos === false) {
    echo "The string '$findme' was not found in the string '$mystring'";
} else {
    echo "The string '$findme' was found in the string '$mystring' at position $pos";
}
 
// It is also possible to ignore the beginning of a string

$newstring = 'abcdef abcdef';
$pos = strpos($newstring, 'a', 1); // $pos = 7, not 0

?>
