A PHP library for sending messages to devices registered through Google Cloud Messaging

See: http://developer.android.com/guide/google/gcm/index.html

Example usage

use \CodeMonkeysRu\GCM;

$sender = new GCM\Sender("YOUR GOOGLE API KEY");

$message = new GCM\Message(
        array("device_registration_id1", "device_registration_id2"),
        array("data1" => "123", "data2" => "string")
);

$message
    ->notification(array("title" => "foo", "body" => "bar"))
    ->setCollapseKey("collapse_key")
    ->setDelayWhileIdle(true)
    ->setTtl(123)
    ->setRestrictedPackageName("com.example.trololo")
    ->setDryRun(true)
    ->setPriority(GCM\MessageMessage::PRIORITY_HIGH)
;

try {
    $response = $sender->send($message);

    if ($response->getNewRegistrationIdsCount() > 0) {
        $newRegistrationIds = $response->getNewRegistrationIds();
        foreach ($newRegistrationIds as $oldRegistrationId => $newRegistrationId){
            //Update $oldRegistrationId to $newRegistrationId in DB
            //TODO
        }
    }

    if ($response->getFailureCount() > 0) {
        $invalidRegistrationIds = $GCMresponse->getInvalidRegistrationIds();
        foreach($invalidRegistrationIds as $invalidRegistrationId) {
            //Remove $invalidRegistrationId from DB
            //TODO
        }

        //Schedule to resend messages to unavailable devices
        $unavailableIds = $response->getUnavailableRegistrationIds();
        //TODO
    }
} catch (GCM\Exception $e) {

    switch ($e->getCode()) {
        case GCM\Exception::ILLEGAL_API_KEY:
        case GCM\Exception::AUTHENTICATION_ERROR:
        case GCM\Exception::MALFORMED_REQUEST:
        case GCM\Exception::UNKNOWN_ERROR:
        case GCM\Exception::MALFORMED_RESPONSE:
            //Deal with it
            break;
    }
}

Also indirect message API available

use \CodeMonkeysRu\GCM;

$sender = new GCM\Sender("YOUR GOOGLE API KEY");

try {
    $response = $sender->sendMessage(
        array("device_registration_id1", "device_registration_id2"),
        array("data1" => "123", "data2" => "string"),
        "collapse_key"
    );

    if ($response->getNewRegistrationIdsCount() > 0) {
        $newRegistrationIds = $response->getNewRegistrationIds();
        foreach ($newRegistrationIds as $oldRegistrationId => $newRegistrationId){
            //Update $oldRegistrationId to $newRegistrationId in DB
            //TODO
        }
    }

    if ($response->getFailureCount() > 0) {
        $invalidRegistrationIds = $GCMresponse->getInvalidRegistrationIds();
        foreach($invalidRegistrationIds as $invalidRegistrationId) {
            //Remove $invalidRegistrationId from DB
            //TODO
        }

        //Schedule to resend messages to unavailable devices
        $unavailableIds = $response->getUnavailableRegistrationIds();
        //TODO
    }
} catch (GCM\Exception $e) {

    switch ($e->getCode()) {
        case GCM\Exception::ILLEGAL_API_KEY:
        case GCM\Exception::AUTHENTICATION_ERROR:
        case GCM\Exception::MALFORMED_REQUEST:
        case GCM\Exception::UNKNOWN_ERROR:
        case GCM\Exception::MALFORMED_RESPONSE:
            //Deal with it
            break;
    }
}

Note about cURL SSL verify peer option

Library has turned off CURLOPT_SSL_VERIFYPEER by default, but you can enable it by passing third parameter into constructor of Sender class.

You need to download root certificates and add them somewhere into your project directory. Then construct Sender object like this:

use \CodeMonkeysRu\GCM;

$sender = new GCM\Sender("YOUR GOOGLE API KEY", false, "/path/to/cacert.crt");
