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

Finds the last occurrence of a needle within a haystack.

In contrast to strrpos(), the return value of iconv_strrpos() 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.
