# PHP

> BullMQ PHP client for adding jobs to queues

The BullMQ PHP package provides a **Queue client** that allows you to add jobs to BullMQ queues from your PHP applications. These jobs can then be processed by workers written in Node.js, Python, or Elixir.

## Overview

BullMQ PHP is designed as a producer-only client, focusing on adding jobs to queues efficiently and reliably.

<Info>
  The PHP package only implements the Queue class (producer side). Workers are not included as PHP's execution model is not well-suited for long-running worker processes. Use Node.js, Python, or Elixir workers to process the jobs.
</Info>

## Key Features

* **Add jobs to queues** - Single and bulk job operations
* **Job scheduling** - Support for delayed jobs
* **Priority queues** - Process important jobs first
* **Job retry** - Configurable retry strategies with backoff
* **Queue management** - Pause, resume, clean, and drain queues
* **Job introspection** - Get job states and queue statistics
* **Parent-child jobs** - Support for job flows and dependencies
* **Interoperability** - Full compatibility with BullMQ workers in Node.js, Python, and Elixir

## Requirements

* PHP 8.1 or higher
* Redis 5.0 or higher (6.2+ recommended)
* Composer

## Use Cases

PHP BullMQ is ideal for:

* Adding background jobs from PHP web applications
* Integrating PHP systems with BullMQ-based job processing infrastructure
* Building hybrid systems where jobs are created in PHP and processed in Node.js, Python, or Elixir
* Scheduling tasks from PHP applications

## Version

Current version: **1.0.1**

## Architecture

The PHP client communicates with Redis using the same Lua scripts as other BullMQ implementations, ensuring full compatibility. Jobs added via PHP are indistinguishable from jobs added via other languages.

## Supported Operations

### Queue Operations

* Add single and bulk jobs
* Get job information and state
* Pause and resume queues
* Clean old jobs
* Drain and obliterate queues
* Retry and promote jobs
* Get job counts and statistics

### Job Options

* Custom job IDs
* Delays and scheduling
* Priority
* Retry attempts and backoff
* Removal policies (removeOnComplete, removeOnFail)
* LIFO ordering
* Parent-child relationships

## Interoperability

Jobs added with the PHP client are fully compatible with BullMQ workers in:

* **Node.js** - Using the official [BullMQ](https://www.npmjs.com/package/bullmq) package
* **Python** - Using the [BullMQ Python](https://pypi.org/project/bullmq/) package
* **Elixir** - Using the [BullMQ Elixir](https://hex.pm/packages/bullmq) package

<Warning>
  **Note on Job Schedulers**: Repeatable/scheduled jobs (cron patterns) should be created from the Node.js side using `JobScheduler`. The PHP client is designed for adding individual jobs, not managing schedulers.
