Have you defined api key .. "Authorization: key=api key". This api key is issued when app is been registered on Google for GCM services. Check this. — AndroidHacker, Dec 04 '13 at 10:43

this is the working script which i have implemented in my own GCM project. Try to run this. Make sure to do changes in the "api_key" and "registrationids".

 <?php
        $api_key = "AIzBpx4XbXkhkjwKd8P-v2d1Jk";
        $registrationIDs = array("APA91bjkj3Rjlo8T_URx15NqvxY2mRyQ");
        $message = "congratulations";
        $url = 'https://android.googleapis.com/gcm/send';
        $fields = array(
                    'registration_ids'  => $registrationIDs,
                    'data'              => array( "message" => $message ),
                    );

        $headers = array(
                        'Authorization: key=' . $api_key,
                        'Content-Type: application/json');

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt( $ch, CURLOPT_POST, true );
        curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
        curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
        $result = curl_exec($ch);
        curl_close($ch);

    echo $result;
    ?>
