}
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 {

echo "Found new job {$job->getId()}\n", var_export($job->getBody(), true), "\n";
$jobQueue->markAsComplete($job);
}

} while (true);
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']);
