C2DM implementation PHP code

Question

I am creating the Android application where C2DM push notification is used. But i have a problem in creating the php code to use c2dm for sending messages. please guide me how to use the php code to send the messages. Actually there is a problem regarding this that how to get client auth token. I have seen the http://code.google.com/android/c2dm/index.html#server url but according to this i have created the android application and i got the registration id also and i also send to the user but how server uses this to send the application.

is there anything needed for the server from the android device to send the messages?.

To register your own server system and obtain the Authorise Tokens (this is what Cpt. Ohlund proposed):

function googleAuthenticate($username, $password, $source="Company-AppName-Version", $service="ac2dm") {               session_start();         if( isset($_SESSION['google_auth_id']) && $_SESSION['google_auth_id'] != null)             return $_SESSION['google_auth_id'];          // get an authorization token         $ch = curl_init();         if(!ch){             return false;         }          curl_setopt($ch, CURLOPT_URL, "https://www.google.com/accounts/ClientLogin");         $post_fields = "accountType=" . urlencode('HOSTED_OR_GOOGLE')             . "&Email=" . urlencode($username)             . "&Passwd=" . urlencode($password)             . "&source=" . urlencode($source)             . "&service=" . urlencode($service);         curl_setopt($ch, CURLOPT_HEADER, true);         curl_setopt($ch, CURLOPT_POST, true);         curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);         curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);         curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);             curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);         curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);          // for debugging the request         //curl_setopt($ch, CURLINFO_HEADER_OUT, true); // for debugging the request          $response = curl_exec($ch);          //var_dump(curl_getinfo($ch)); //for debugging the request         //var_dump($response);          curl_close($ch);          if (strpos($response, '200 OK') === false) {             return false;         }          // find the auth code         preg_match("/(Auth=)([\w|-]+)/", $response, $matches);          if (!$matches[2]) {             return false;         }          $_SESSION['google_auth_id'] = $matches[2];         return $matches[2];     } 

To send a message to a phone:

// $msgType: all messages with same type may be "collapsed": if multiple are sent, // only the last will be received by phone.  function sendMessageToPhone($authCode, $deviceRegistrationId, $msgType, $messageText) {              $headers = array('Authorization: GoogleLogin auth=' . $authCode);             $data = array(                 'registration_id' => $deviceRegistrationId,                 'collapse_key' => $msgType,                 'data.message' => $messageText //TODO Add more params with just simple data instead                        );              $ch = curl_init();              curl_setopt($ch, CURLOPT_URL, "https://android.apis.google.com/c2dm/send");             if ($headers)             curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);             curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);             curl_setopt($ch, CURLOPT_POST, true);             curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);             curl_setopt($ch, CURLOPT_POSTFIELDS, $data);               $response = curl_exec($ch);              curl_close($ch);              return $response;         }
