    if ($data_array != null) {
        foreach($data_array as $key=>$value) { $data .= $key.'='.$value.'&'; }

    $ch = curl_init($url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);

}

// Verify user with Appota User API
function verify_appota_user($appota_access_token, $appota_userid) {
    $url = sprintf('https://api.gamota.com/game/get_user_info?access_token=%s', $appota_access_token);
    $data = call_curl_get($url, null);
    if(!$data['status'])
        return false;
    else {
        if($data["data"]["user_id"] == $appota_userid)
            return true;
        else
            return false;
