strrchr

(PHP 4, PHP 5, PHP 7)

strrchrFind the last occurrence of a character in a string

Description

strrchr ( string $haystack , string $needle ) : string|false

This function returns the portion of haystack which starts at the last occurrence of needle and goes until the end of haystack.

Parameters

haystack

The string to search in

needle

If needle contains more than one character, only the first is used. This behavior is different from that of strstr().

Prior to PHP 8.0.0, if needle is not a string, it is converted to an integer and applied as the ordinal value of a character. This behavior is deprecated as of PHP 7.3.0, and relying on it is highly discouraged. Depending on the intended behavior, the needle should either be explicitly cast to string, or an explicit call to chr() should be performed.

Return Values

This function returns the portion of string, or false if needle is not found.

Changelog

Version Description
8.0.0 Passing an int as needle is no longer supported.
7.3.0 Passing an int as needle has been deprecated.

Examples

$last = substr(strrchr($text, 10), 1 );
?>
