strstr -- Find first occurrence of a string


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

$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.

strstr() has been binary safe since PHP 4.3.0

See also preg_match(), stristr(), strpos(), strrchr(), and substr().
