Installation

composer require long-running/core

Symfony

If you are using Symfony, make sure to enable the bundle:

<?php
// config/bundles.php

return [
    // ...
    LongRunning\Core\Bundle\LongRunningBundle::class => ['all' => true],
];

How to use?

<?php

final class MyCleaner implements \LongRunning\Core\Cleaner
{
    public function cleanUp() : void
    {
        echo "Cleaning up memory!";
    }
}

$cleaner = new \LongRunning\Core\DelegatingCleaner([
    new MyCleaner(),
]);

while (true) {
    // Do heavy work, like processing jobs from a queue
    echo "Doing heavy work";
    sleep(1);
    echo "Done with heavy work";

    // Cleanup things
    $cleaner->cleanUp();
}

If you are using Symfony, any service that implements the LongRunning\Core\Cleaner interface will be autoconfigured and added to the LongRunning\Core\DelegatingCleaner.

The LongRunning\Core\DelegatingCleaner is aliased to LongRunning\Core\Cleaner.

That means that you can inject the LongRunning\Core\Cleaner service in your worker and it will call all configured cleaners on cleanUp():

<?php

namespace App;

use LongRunning\Core\Cleaner;

final class Worker
{
    private Cleaner $cleaner;

    public function __construct(Cleaner $cleaner)
    {
        $this->cleaner = $cleaner;
    }

    public function doWork() : void
    {
        while (true) {
            // Do heavy work, like processing jobs from a queue
            echo "Doing heavy work";
            sleep(1);
            echo "Done with heavy work";

            // Cleanup things
            $this->cleaner->cleanUp();
        }
    }
}
