Its a online token queue management system suitable for token dispensing machine. It is created using Laravel 5 PHP f.

A unified front-end for different queuing backends. Includes a REST server, CLI interface and daemon runners.

Why PHP-Queue?

Implementing a queueing system (eg. Beanstalk, Amazon SQS, RabbitMQ) for your application can be painful:

  • Which one is most efficient? Performant?
  • Learning curve to effectively implement the queue backend & the libraries.
  • Time taken to develop the application codes.
  • Vendor locked in, making it impossible to switch.
  • Requires massive code change (ie. not flexible) when use case for the queue changes.
System

PHP-Queue hopes to serve as an abstract layer between your application code and the implementation of the queue.

Benefits

  • Job Queue is Backend agnostic

    Just refer to the queue by name, what it runs on is independent of the application code. Your code just asks for the next item in the PHPQueueJobQueue, and you'll get a PHPQueueJob object with the data and jobId.

  • Flexible Job Queue implementation

    You can decide whether each PHPQueueJobQueue only carries 1 type of work or multiple types of target workers. You control the retrieval of the job data from the Queue Backend and how it is instantiated as a PHPQueueJob object. Each PHPQueueJob object carries information on which workers it is targeted for.

  • Independent Workers

    Workers are independent of Job Queues. All it needs to worry about is processing the input data and return the resulting data. The queue despatcher will handle the rest. Workers will also be chainable.

  • Powerful

    The framework is deliberately open-ended and can be adapted to your implementation. It doesn't get in the way of your queue system.

    We've build a simple REST server to let you post job data to your queue easily. We also included a CLI interface for adding and triggering workers. All of which you can sub-class and overwrite.

    You can also include our core library files into your application and do some powerful heavy lifting.

    Several backend drivers are bundled:

    • Memcache
    • Redis
    • MongoDB
    • CSVThese can be used as the primary job queue server, or for abstract FIFO or key-value data access.

Installation

Installing via Composer

Composer is a dependency management tool for PHP that allows you to declare the dependencies your project needs and installs them into your project. In order to use the PHP-Queue through Composer, you must do the following:

Job

  1. Add 'coderkungfu/php-queue' as a dependency in your project's composer.json file. Visit the Packagist page for more details.

  2. Download and install Composer.

  1. Install your dependencies.

  1. All the dependencies should be downloaded into a vendor folder.

  2. Require Composer's autoloader.

Getting Started

You can have a look at the Demo App inside .vendorcoderkungfuphp-queuesrcdemo folder for a recommended folder structure.

  • htdocs folder
    • .htaccess
    • index.php
  • queues folder
    • <QueueNameInCamelCase>Queue.php
  • workers folder
    • <WorkerNameInCamelCase>Worker.php
  • runners folder
  • cli.php file
  • config.php file

I would also recommend putting the autoloader statement and your app configs inside a separate config.php file.

Recommended config.php file content:

Altenative config.php file:

You can also declare your application's namespace for loading the Queues and Workers.

PHP-Queue will attempt to instantiate the PHPQueueJobQueue and PHPQueueWorker classes using your namespace - appended with the queue/worker name. (ie. MyFabulousAppQueuesFacebook).

It might be advisable to use Composer's Custom Autoloader for this.

Note:
If you declared PHPQueueBase::$queue_path and/or PHPQueueBase::$worker_path together with the namespace, the files will be loaded with require_once from those folder path AND instantiated with the namespaced class names.

REST Server

The default REST server can be used to interface directly with the queues and workers.

Copy the htdocs folder in the Demo App into your installation. The index.php calls the PHPQueueREST::defaultRoutes() method - which prepares an instance of the RespectRest REST server. You might need to modify the path of config.php within the index.php file.

Recomended installation:use a new virtual host and map the htdocs as the webroot.

  1. Add new job.
  1. Trigger next job.

Read the full documentation on RespectRest to further customize to your application needs (eg. Basic Auth).

Command Line Interface (CLI)

Copy the cli.php file from the Demo App into your installation. This file implements the PHPQueueCli class. You might need to modify the path of config.php within the cli.php file.

  1. Add new job.
  1. Trigger next job.

You can extend the PHPQueueCli class to customize your own CLI batch jobs (eg. import data from a MySQL DB into a queue).

Runners

You can read more about the Runners here.

Php Message Queue

Interfaces

The queue backends will support one or more of these interfaces:

  • AtomicReadBuffer

This is the recommended way to consume messages. AtomicReadBuffer provides thepopAtomic($callback) interface, which rolls back the popped record if thecallback returns by exception. For example:$queue = new PHPQueueBackendPDO($options);

The message will only be popped if churn() returns successfully.

  • FifoQueueStore

A first in first out queue accessed by push and pop.
