FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Last predis version tested is 1.0.1.
Last Celery version tested is 3.1.19 (but check out the celery4 branch)
API documentation is dead, help wanted
POSTING TASKS
$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'] = $result;
// and use this variable in an AJAX call or whatevertip: if using RabbitMQ guest user, set "/" vhost
READING ASYNC RESULTS
while (!$result->isReady()) {
sleep(1);
echo '...';
}
if ($result->isSuccess()) {
echo $result->getResult();
} else {
echo "ERROR";
echo $result->getTraceback();
}GET ASYNC RESULT MESSAGE
$c = new \Celery\Celery('localhost', 'myuser', 'mypass', 'myvhost');
$message = $c->getAsyncResultMessage('tasks.add', 'taskId');PYTHON-LIKE API
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;

CONNECTING VIA SSL
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, false, $ssl_options);CONNECTING TO REDIS
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 */
);
