You can try my solution:

function checkServer( $domains=array(), $url ) {
    foreach ( $domains as $domain ) {
        if ( strpos($url, $domain ) > 0) {
            return true;
        } else {
            return false;
        }
    }
}

Use:

if( checkServer(array("youtube.com","youtu.be"), $url ) ) {
    //is Youtube url
}
elseif( checkServer(array("vimeo.com"), $url ) ) {
    //is Vimeo
}
elseif ( checkServer(array("any domain"), $url ) ) {
    //is Any Domain
}else {
    //unknow domain
}
