Neuron-PHP Job Scheduler

Overview

Installation

composer require neuron-php/jobs

Configure the application to use psr-4 autoloading in composer.json as the application relies on the autoloader to create the job objects.

Composer snippet:

  "autoload": {
    "psr-4": {
      "App\\": "src/"
    }

Configuration

Example Directory Structure

├── composer.json
├── config
│   ├── config.yaml
│   └── schedule.yaml 
├── src  
│   └── Jobs
│       └── MyJob.php
└── vendor 

Application

The application configuration is loaded from config/config.yaml

Example config.yaml:

logging:
  destination: \Neuron\Log\Destination\StdOut
  format: \Neuron\Log\Format\PlainText
  level: debug

system:
  timezone: US/Eastern
  base_path: /path/to/app

Schedule

The job schedule is loaded from config/schedule.yaml

Example schedule.yaml:

schedule:
  testJobWithArgs:
    class: App\Jobs\ImportData
    cron: "5 * * * *"
    args:
      doSomething: true
      dontDoSomething: false

  testJobWithOutArgs:
    class: App\Jobs\SendReminderEmail
    cron: "15 * * * *"

• class: The class to instantiate and run.
• cron: The cron expression for the job schedule.
• args: An array of arguments to pass to the job.

Job Classes

Job classes must implement the Neuron\Jobs\IJob interface.

Example Job class:

namespace App\Jobs;

use Neuron\Jobs\IJob;
use Neuron\Log\Log;

class ExampleJob implements IJob
{
    public function getName() : string
    {
        return 'TestJob';
    }

    public function run( array $Argv = [] ) : mixed
    {
        Log::debug( "TestJob::run( {$Argv['parameterName']} )" );
        return true;
    }
}

Running the Scheduler

Infinite Polling

./vendor/bin/schedule

This will run the scheduler in an infinite polling loop, polling every 60 seconds by default.

The polling interval seconds can be changed with the --interval option.

./vendor/bin/schedule --interval 5

Single Poll

The scheduler can also be run to perform a single poll of the schedule by using the --poll option. For best results, the schedule should be run with the --poll option in a cron job and ran once per minute.

./vendor/bin/schedule --poll
