Twilio Laravel 4使用国家/地区代码验证电话号码

Question

How to validate phone number with country code using laravel 4

Below is my code

use Aloha\Twilio\Twilio;

    $phoneNumber = new PhoneNumber($this->phoneNo, $this->countryCode);

        // Your Account Sid and Auth Token from twilio.com/user/account
        $sid = "11111";
        $token = "rtrg";
        $client = new Lookups_Services_Twilio($sid, $token);

        $number = $client->phone_numbers->get($this->phoneNo, array("CountryCode" => $this->countryCode, "Type" => "carrier"));

I'm getting following error:

Class 'Managers\Lookups_Services_Twilio' not found

Please advise.
