i have this url

how to get video id from it by regular expression

Answer 1

$url = "http://youtu.be/JaFfJN_iKdA";
if (preg_match('%(?:youtube\.com/(?:user/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $url, $result)) {
    $video_id = $result[1];
}

That will work for a bunch of common YT URL formats including the one you posted.
