Job Queue implementation.
Install
Via Composer
$ composer require phlib/jobqueue
or
"require": { "phlib/jobqueue": "*" }
Basic Usage
Bootstrap
$beanstalk = (new \Phlib\Beanstalk\Factory())->create('localhost'); $db = new \Phlib\Db\Adapter(['host' => '127.0.0.1', 'dbname' => 'example']); $scheduler = new \Phlib\JobQueue\DbScheduler($db, 300, 600); $jobQueue = new \Phlib\JobQueue\Beanstalk\Scheduled($beanstalk, $scheduler);
Producer
$delay = strtotime('+1 week') - time(); $jobQueue->put('my-queue', ['my' => 'jobData'], ['delay' => $delay]);
Consumer
do { while ($job = $jobQueue->retrieve($queue)) { echo "Found new job {$job->getId()}\n", var_export($job->getBody(), true), "\n"; $jobQueue->markAsComplete($job); } usleep(500); } while (true);
Jobqueue Script
The script has a dependency on two constructed objects. The Job Queue interface and the Scheduler interface. In order to provide this the following describes how they are injected into the script.
jobqueue-config.php (can be located in the root or config
folder.
<?php $app = new MyApp(); return new \Phlib\JobQueue\Console\MonitorDependencies($app['jobqueue'], $app['scheduler']);
