function getFacebookIdFromUrlandUsername($url,$access_token) {
/**

$correctURLPattern = '/^https?:\/\/(?:www|m)\.facebook.com\/(?:profile\.php\?id=)?([a-zA-Z0-9\.]+)$/';
if (!preg_match($correctURLPattern, $url, $matches)) {
    $getinf = 'https://graph.facebook.com/' .$url.'/?access_token='.$access_token;
    $info = json_decode(file_get_contents($getinf), true);
    return$info;
