PHP client capable of executing Celery tasks and reading asynchronous results.
Uses AMQP extension from PECL, the PHP AMQP implementation or Redis and the following settings in Celery:
result_serializer = 'json'
result_expires = None
task_track_started = False
The required PECL-AMQP version is at least 1.0. Last version tested is 1.4.
Last PHP-amqplib version tested is 2.5.1.
Last predis version tested is 1.0.1.
Requires Celery 4.0+.
API documentation is dead, help wanted
$c = new \Celery\Celery('localhost', 'myuser', 'mypass', 'myvhost');
$result = $c->PostTask('tasks.add', array(2,2));
// The results are serializable so you can do the following:
$_SESSION['celery_result'] = $result;
// and use this variable in an AJAX call or whatever
tip: if using RabbitMQ guest user, set "/" vhost
while (!$result->isReady()) {
sleep(1);
echo '...';
}
if ($result->isSuccess()) {
echo $result->getResult();
} else {
echo "ERROR";
echo $result->getTraceback();
}
$c = new \Celery\Celery('localhost', 'myuser', 'mypass', 'myvhost');
$message = $c->getAsyncResultMessage('tasks.add', 'taskId');
An API compatible to AsyncResult in Python is available too.
$c = new \Celery\Celery('localhost', 'myuser', 'mypass', 'myvhost');
$result = $c->PostTask('tasks.add', array(2,2));
$result->get();
if ($result->successful()) {
echo $result->result;
}

Development process and goals.
Connecting to a RabbitMQ server that requires SSL is currently only possible via PHP-amqplib to do so you'll need to create a celery object with ssl options:
$ssl_options = [
'cafile' => 'PATH_TO_CA_CERT_FILE',
'verify_peer' => true,
'passphrase' => 'LOCAL_CERT_PASSPHRASE',
'local_cert' => 'PATH_TO_COMBINED_CLIENT_CERT_KEY',
'CN_match' => 'CERT_COMMON_NAME'
];
$c = new \Celery\Celery($host, $user, $password, $vhost, 'celery', 'celery', 5671, false, 0, $ssl_options);
Refer to files in testscenario/ for examples of celeryconfig.py.
$c = new \Celery\Celery(
'localhost', /* Server */
'', /* Login */
'test', /* Password */
'wutka', /* vhost */
'celery', /* exchange */
'celery', /* binding */
6379, /* port */
'redis' /* connector */
);
