strstr

(PHP 4, PHP 5)

strstr — Find first occurrence of a string

Description

string strstr ( string $haystack , string $needle , bool $before_needle )

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

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

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

Parameters

haystack

The input string.

needle

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

before_needle

If TRUE (the default is FALSE), strstr() returns the part of the haystack before the first occurence of the needle .

Return Values

Returns the portion of string, or FALSE if needle is not found.
