Using PHP to find unicode of a character [duplicate]

Answer 1

To be unicode aware you should try this one (http://us.php.net/manual/en/function.ord.php)

function uniord($u) {
    $k = mb_convert_encoding($u, 'UCS-2LE', 'UTF-8');
    $k1 = ord(substr($k, 0, 1));
    $k2 = ord(substr($k, 1, 1));
    return $k2 * 256 + $k1;
}
