strpos() - string

Find the numeric position of the first occurrence of
   needle in the haystack string.

Parameters : 
 haystack - The string to search in. 
 needle - If needle is not a string, it is converted
       to an integer and applied as the ordinal value of a character. 
 offset - If specified, search will start this number of characters counted from
       the beginning of the string. Unlike strrpos() and
       strripos(), the offset cannot be negative. 

Syntax

mixed strpos
    ( string $haystack
   , mixed $needle
   [, int $offset = 0
  ] )

Example

<?php$mystring = 'abc';$findme   = 'a';$pos = strpos($mystring, $findme);// Note our use of ===.  Simply == would not work as expected// because the position of 'a' was the 0th (first) character.if ($pos === false) {    echo "The string '$findme' was not found in the string '$mystring'";} else {    echo "The string '$findme' was found in the string '$mystring'";    echo " and exists at position $pos";}?>
