CI Status
Version
PHP version

This PHP program, based on the unmaintained sourc7/FCMStream repository, allows receiving and sending messages with the XMPP Protocol using Firebase Cloud Messaging.

INSTALLATION

composer require baudev/fcm-xmpp  

EXAMPLES

• Create an index.php file and write into it one of the two following script (method1 or method2). Don't forget replacing : SENDER_ID, SERVER KEY.
• Run the script: php index.php

Note: examples are provided in the directory examples. More explanations can be found into the wiki page.

1. Using a class (best solution):

class YOURCLASSNAME extends \FCMStream\Core {  
  
	public function onSend(string $from, string $messageId, Actions $actions) { 
		 // TODO: Implement onSend() method. 
	 }  
	 
	public function onReceipt(string $from, string $messageId, string $status, int $timestamp, Actions $actions)
         {
             // TODO: Implement onReceipt() method. 
         }
 
	public function onReceiveMessage($data, int $timeToLive, string $from, string $messageId, string $packageName, Actions $actions) { 
		// we answer to the message received 
		$message = new \FCMStream\Message();  
		$message->setTo($from);  
		$message->setMessageId("message_id_test");  
		$message->setPriority(\FCMStream\Message::PRIORITY_HIGH);  
		$message->setData(array("test" => "Hello World!")); 
		 
		$actions->sendMessage($message);
	}  
	
	/**
	 * The method is executed each X microseconds.
	 * To enable this method, you must execute enableOnLoopMethod()
	 * !! Warning !! Enabling this method can increase a lot the usage of your CPU!
	 * @param Actions $actions
	 */
	public function onLoop(Actions $actions)
	{
		// TODO: Implement onLoop() method. 
	}

	public function onFail(?string $error, ?string $errorDescription, ?string $from, ?string $messageId, Actions $actions) { 
		// TODO: Implement onFail() method. 
	}  
	
	public function onExpire(string $from, string $newFCMId, Actions $actions) { 
	    // TODO: Implement onExpire() method. 
	}
}  
  
$test = new YOURCLASSNAME('SENDER_ID', 'SERVER KEY', 'debugfile.txt', \FCMStream\helpers\Logs::DEBUG); 
// $test->enableOnLoopMethod(5 * 1000 * 1000); // enables the onLoop method. She will be called each 5 seconds. 
// Before uncommenting the previous line, see https://github.com/baudev/Firebase-Cloud-Messaging-FCM-XMPP/wiki/References#enableonloopmethodmicroseconds
$test->stream();  

2. Using function callback parameters:

$test = new FCMStream\Callbacks('SENDER_ID', 'SERVER KEY', 'debugfile.txt', \FCMStream\helpers\Logs::ANY);  
  
// onSend callback  
$test->setOnSend(function (string $from, string $messageId, Actions $actions){  
	// TODO: Implement onSend() method.
  });  
  
// onReceipt callback
$test->setOnReceipt(function (string $from, string $messageId, string $status, int $timestamp, Actions $actions) {
	// TODO: Implement onReceipt() method.
});
  
// onReceiveMessage callback  
$test->setOnReceiveMessage(function ($data, int $timeToLive, string $from, string $messageId, string $packageName, Actions $actions){ 
	// we answer to the message received 
	$message = new \FCMStream\Message();  
	$message->setTo($from);  
	$message->setMessageId("message_id_test");  
	$message->setPriority(\FCMStream\Message::PRIORITY_NORMAL);  
	$message->setData(array("test" => "Hello World!"));  
	
	$actions->sendMessage($message);  
});

// onLoop callback
// To enable this method, you must execute enableOnLoopMethod()
// !! Warning !! Enabling this method can increase a lot the usage of your CPU!
$test->setOnLoop(function (Actions $actions) {
	// TODO: Implement onLoop() method. 
});
  
// onFail callback  
$test->setOnFail(function (?string $error, ?string $errorDescription, ?string $from, ?string $messageId, Actions $actions) { 
	// TODO: Implement onFail() method. 
  });  
  
// onExpire callback  
$test->setOnExpire(function (string $from, string $newFCMId, Actions $actions){  
	// TODO: Implement onExpire() method. 
  });  
  
// $test->enableOnLoopMethod(5 * 1000 * 1000); // enables the onLoop method. She will be called each 5 seconds.
// Before uncommenting the previous line, see https://github.com/baudev/Firebase-Cloud-Messaging-FCM-XMPP/wiki/References#enableonloopmethodmicroseconds
$test->stream();  

USAGE

1. Downstream Messages: server-to-device through FCM

2. Upstream Messages: device-to-server through FCM

TODO

• Add more comments
• Add methods for responding easily, to set message priority and so on. Notification property is not handled yet
• Improve README
• Add more tests
