strrchr - Find the last occurrence of a character in a string

SYNOPSIS

       string strrchr (string  $haystack, mixed  $needle)

DESCRIPTION

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

PARAMETERS

	      o $haystack
		- The string to search in

	      o $needle
		-  If  $needle	contains  more	than one character, only the first is used. This behavior is different from that of strstr(3).	If
		$needle is not a string, it is converted to an integer and applied as the ordinal value of a character.

RETURN VALUES

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