Linio Queue abstracts work queues, used to distribute time-consuming tasks among multiple workers.
The recommended way to install Linio Queue is through composer.
{
"require": {
"linio/queue": "~3.0"
}
}To run the test suite, you need install the dependencies via composer, then run PHPUnit.
$ composer install
$ phpunit
The library is very easy to use: first, you have to register the service. For Silex, a service provider is included. Just register it:
<?php
use Linio\Component\Queue\QueueService;
use Linio\Component\Queue\Adapter;
$queue = new QueueService();
$queue->setAdapter(new Adapter\RabbitAdapter([
'host' => 'localhost',
'port' => 5672,
'username' => 'guest',
'password' => 'guest',
'vhost' => '/'
]));In order to create a work queue, you must extend the abstract class Job:
<?php
use Linio\Component\Queue\Job;
class HelloWorldJob extends Job
{
public function perform()
{
echo sprintf("Hello %s!\n", $this->payload);
$this->finish();
}
}Note that you must always finish() a job to remove it from the queue. You
can also fail() jobs. Now, in order to publish messages to a work queue:
<?php
use Linio\Component\Queue\QueueService;
$queue = new QueueService();
$queue->add(new HelloWorldJob('John')); // "John" is the payloadAnd to consume messages from the work queue:
<?php
use Linio\Component\Queue\QueueService;
$queue = new QueueService();
$queue->perform(new HelloWorldJob());
