[PHP] GCM푸시 요청 서버 예제

Example usage

$apiKey = "YOUR GOOGLE API SERVER KEY";

$devices = array('YOUR REGISTERED DEVICE ID');

$message = "The message to send";

$gcpm = new GCMPushMessage($apiKey);

$gcpm->setDevices($devices);

$response = $gcpm->send($message, array('title' => 'Test title'));

클래스를 생성하고 API키와 휴대폰의 REG ID값을 넣어주면 GCM을 전송가능하다.
