PHP port of Kue (Node.js)

Note: It's under develop now!

The goal is: Supply a simple and strong way to process the background jobs using PHP

Install

Add "kue/kue": "*" to your composer.json, then:

composer install

Overview

Usage

Create Queue

// Connect to redis "localhost:6379"
$kue = Kue::createQueue();

Create with redis config

// Connect "redis_server:6379" and select db to "1"
$kue = Kue::createQueue(array('host' => 'redis_server', 'db' => 1));

Node Compatible mode

In this mode, you can create job using PHP, and process job with Node.js

$kue = Kue::createQueue();

$kue->originalMode(true);

The original mode will create job structure same as Node.js, The default mode change a little structure because of some reasons for simply using in PHP.

Create Job

$kue = Kue::createQueue();

$kue->create('email', array(
    'to' => 'hfcorriez@gmail.com',
    'subject' => 'Reset your password!',
    'body' => 'Your can reset your password in 5 minutes. Url: http://xxx/reset'
))->save();

Create job with priority

Priority will decide your job process order:

$kue = Kue::createQueue();

$kue->create('email', array(
    'to' => 'hfcorriez@gmail.com',
    'subject' => 'Reset your password!',
    'body' => 'Your can reset your password in 5 minutes. Url: http://xxx/reset'
))->priority('high')->save();

### Create job with timing

Timing will trigger job at given time, see follow examples:

$kue = Kue::createQueue();

$kue->create('email', array(
    'to' => 'hfcorriez@gmail.com',
    'subject' => 'Reset your password!',
    'body' => 'Your can reset your password in 5 minutes. Url: http://xxx/reset'
))->timing('tomorrow')->save();

Timing format is process as PHP date and time formats, You can use:

  • Next Monday
  • +1 days
  • last day of next month
  • 2013-09-13 00:00:00
  • and so on..

Create Job with delay time

The follow example will delay job in 3600 seconds:

$kue = Kue::createQueue();

$kue->create('email', array(
    'to' => 'hfcorriez@gmail.com',
    'subject' => 'Reset your password!',
    'body' => 'Your can reset your password in 5 minutes. Url: http://xxx/reset'
))->delay(3600)->save();

### Create job with attempts

When the job failed, the next example will show how to attempts:

$kue = Kue::createQueue();

$kue->create('email', array(
    'to' => 'hfcorriez@gmail.com',
    'subject' => 'Reset your password!',
    'body' => 'Your can reset your password in 5 minutes. Url: http://xxx/reset'
))->attempts(5)->save();

Process job

Note: $kue->process is blocking

To process the jobs, you must write a script and run as daemon:

$kue = Kue::createQueue();

// Process the `email` type job
$kue->on('process:email', function($job){
    // Process logic
    $data = $job->data
    mail($data['to'], $data['subject'], $data['body']);
});

// Will blocking process to subscribe the queue
$kue->process();

I'll supply the daemon script and service in future.

Process given type

If your want to write a script to process the given type.

$kue = Kue::createQueue();

// Process the `email` type job
$kue->on('process:email', function($job){
    // Process logic
    $data = $job->data
    mail($data['to'], $data['subject'], $data['body']);
});

// Process `email` type only
$kue->process('email');

or using Node.js style

$kue = Kue::createQueue();

// Process `email` type only
$kue->process('email', function($job){
   // Process logic
   $data = $job->data
   mail($data['to'], $data['subject'], $data['body']);
});

Process all types

$kue = Kue::createQueue();

// Process all types
$kue->process(function($job){
   // Process logic
   log($job->type . ' processed');
});
