PHP Manual for

strstr

(PHP 3, PHP 4 )

strstr -- Find first occurrence of a string

Description

string strstr ( string haystack, string needle)

Returns part of haystack string from the first occurrence of needle to the end of haystack .

If needle is not found, returns FALSE .

If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.

Note: This function is case-sensitive. For case-insensitive searches, use stristr().

Example 1. strstr() example

<?php
$email
= 'user@example.com';
$domain = strstr($email, '@');
echo
$domain; // prints @example.com
?>

Note: If you only want to determine if a particular needle occurs within haystack , use the faster and less memory intensive function strpos() instead.
