Queue
, (*1)
This library is a Queueing Aystem abstraction layer. It enables you to implement any queueing system in your application,
without having to depend on the actual implementation of the queueing system you choose., (*2)
Attention: You will need a Process Control System like supervisord to keep your workers going., (*3)
Use Case
Queueing system, (*4)
Say you want to notify multiple users when a new comment is placed on a forum thread. Sending these email on the spot might
slow down your application significantly when many emails need to be send. When using a Queueing System you can delay this
action by adding the Jobs to a Queue. A worker will pick up these Jobs asynchronously from you web process. This way your
application is future proof and you will have a much easier time scaling in the future., (*5)
Library, (*6)
When you decide to use this library, you do not depend on the queueing system implementation. You can plug the driver of your
choice. You might choose a basic mysql version to get started and when you need more performance go for something like
beanstalkd or RabbitMQ., (*7)
Code example
<?php
require_once(__DIR__ . '/vendor/autoload.php');
use Queue\Queue;
use Queue\Job\Job;
use Queue\Executor\JobExecutor;
$driver = new QueueDriver(); // Use your driver.
$queue = new Queue($driver);
// Add a job to the queue
$queue->addJob(new Job('notify_forum_thead', ['threadId' => 12]));
<?php
require_once(__DIR__ . '/vendor/autoload.php');
use Queue\Queue;
use Queue\Worker\Worker;
$driver = new QueueDriver(); // Use your driver.
$queue = new Queue($driver);
$worker = new Worker($queue, new JobExecutor(), 1);
$worker->run();
