iconv_strrpos - Finds the last occurrence of a needle within a haystack

SYNOPSIS
       int iconv_strrpos (string  $haystack, string  $needle, [string  $charset = ini_get("iconv.internal_encoding")])

DESCRIPTION
	Finds the last occurrence of a $needle within a $haystack.

	In contrast to strrpos(3), the return value of iconv_strrpos(3) is the number of characters that appear before the needle, rather than the
       offset in bytes to the position where the needle has been found. The characters are counted on the basis of  the  specified  character  set
       $charset.

PARAMETERS
	      o $haystack
		- The entire string.

	      o $needle
		- The searched substring.

	      o $charset
		- If $charset parameter is omitted, $string are assumed to be encoded in iconv.internal_encoding.

	If $haystack or $needle is not a string, it is converted to a string and applied as the ordinal value of a character.

RETURN VALUES
	Returns the numeric position of the last occurrence of $needle in $haystack.

	If $needle is not found, iconv_strrpos(3) will return FALSE.

       Warning

	      This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on
	      Booleans for more information. Use the === operator for testing the return value of this function.
