PHP-Resque usage

PHP-Resque Usage

PHP-Resque is an extension library for PHP for Resque, which enables PHP to use Resque. Resque is A background process system developed based on Redis. Compared with other Queue systems, Resque's design is very simple and fully utilizes the characteristics of Redis.

1. Install php-resque

Enter the project root directory, composer install php-resque

composer require chrisboulton/php-resque

2. Common methods

1. Connect to redis

// setBackend($server, $database = 0)
Resque::setBackend('127.0.0.1:6379');

2. Add work to the queue

// enqueue($queue, $class, $args = null, $trackStatus = false)
$token = Resque::enqueue('default', 'My_Job', ['name'=>'test'], true);

3. Check the work status

$status = (new Resque_Job_Status($token))->get();

4. Stop (remove) the job

(new Resque_Job_Status($token))->stop();

3. Resident task processing queue (example: worker.php)

// 处理 default 队列；也可以填 *，代表所有队列
$worker = new Resque_Worker('default');
// LOG_NONE 不写日志, LOG_NORMAL 普通，LOG_VERBOSE 详细
$worker->logLevel = Resque_Worker::LOG_VERBOSE;
// 队列处理时间间隔，单位：秒
$worker->work(5);

Note: worker.php must be executed through the command line and resides in the background, /usr/local/php/bin/php /xxx/xxx/worker.php

4. Classes for processing work

class My_Job
{
    /**
     * 前置操作
     * @return void
     */
    public function setUp()
    {
        // ... Set up environment for this job
    }
    /**
     * 消费队列
     * @return void
     */
    public function perform()
    {
        // execute a job
    }
    /**
     * 后置操作
     * @return void
     */
    public function tearDown()
    {
        // ... Remove environment for this job
    }
}
