FrankenPHP Queue

A FrankenPHP extension that allows you to send messages in queues and handle them asynchronously.

It can be used as a lightweight, in-process replacement for queues systems like RabbitMQ, Beanstalkd and Redis and can be used with Symfony Messenger and Laravel Queues.

Warning

This extension is highly experimental and not recommended for production use. The public API may change at any time without notice.

Installation

First, if not already done, follow the instructions to install a ZTS version of libphp and xcaddy. Then, use xcaddy to build FrankenPHP with the frankenphp-etcd module:

CGO_ENABLED=1 \
CGO_CFLAGS=$(php-config --includes) \
CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" \
xcaddy build \
    --output frankenphp \
    --with github.com/dunglas/frankenphp-queue \
    --with github.com/dunglas/frankenphp/caddy \
    --with github.com/dunglas/mercure/caddy \
    --with github.com/dunglas/vulcain/caddy
    # Add extra Caddy modules and FrankenPHP extensions here

That's all! Your custom FrankenPHP build contains the frankenphp-queue extension.

Usage

Register The Queue

Register the queue in your Caddyfile:

{
	frankenphp
	frankenphp_queue {
 		# All directives are optional
 		worker queue-worker.php
 		name m#Queue
 		size 10000
 		min_threads 32 # defaults to the number of CPUs of the machine
    }
}

localhost {
    root public/
	php_server
}

Write The Worker Script

<?php

// queue-worker.php

// Handler outside the loop for better performance (doing less work)
$handler = static function (mixed $data)  {
    // Your logic here	
};

$maxRequests = (int)($_SERVER['MAX_REQUESTS'] ?? 0);
for ($nbRequests = 0; !$maxRequests || $nbRequests < $maxRequests; ++$nbRequests) {
    $keepRunning = \frankenphp_handle_request($handler);

    // Call the garbage collector to reduce the chances of it being triggered in the middle of the handling of a request
    gc_collect_cycles();

    if (!$keepRunning) {
      break;
    }
}

Dispatch Messages

<?php

// public/index.php

frankenphp_queue('Hello, Kévin!');

echo 'Data dispatched to an async worker.';

Symfony Messenger Transport

Transport for Symfony Messenger is provided in tests, it will be contributed to Symfony when the extension will be more mature.
