       if(!$ch){
           return false;

        preg_match("/(Auth=)([\w|-]+)/", $response, $matches);

   // send message to android,  The message size limit is 1024 bytes in android

  function c2dmSendMessageToPhone($authCode, $deviceRegistrationId, $msgType, $messageText,$extraArr) {

            $data2 = array();
            // append 'data' string in key of the array
            if(!empty($extraArr)){
                    foreach($extraArr as $k => $v){
                        $data2['data.'.$k] = $v;
                        unset($extraArr[$k]);
                    }
            }

            $data = array_merge($data1,$data2);

Everyone tuning in into this topic should be aware of a change at Google:

C2DM is deprecated and has been replaced by Google Cloud Messaging for Android (GCM). Google's statement:

Important: C2DM has been officially deprecated as of June 26, 2012.
This means that C2DM has stopped accepting new users and quota requests. 
No new features will be added to C2DM. However, apps using C2DM will continue to work. 
Existing C2DM developers are encouraged to migrate to the new version of C2DM, 
called Google Cloud Messaging for Android (GCM).
See the C2DM-to-GCM Migration document for more information.
Developers must use GCM for new development.

There is a demo app tutorial for GCM and also for migration from C2DM.
