PHP Luminova: Scheduling Tasks for Cron Job Execution

Last updated: 2025-08-22 12:42:25

The Cron class is the central configuration for defining and scheduling tasks to be executed by the cron task manager. It extends the CoreCronTasks class provided by Luminova Core and allows you to schedule services and their corresponding execution intervals.

Overview

The Cron class is located in the /app/Config/ namespace and defines tasks to be executed by implementing the schedule method. This method specifies the services (controller methods) to be executed at defined intervals.

Class Definition

Class namespace: \App\Config\Cron
File path: /app/Config/Cron.php
Parent Class: Luminova\Foundation\CoreCronTasks
This class is marked as final and can't be subclassed

Methods

schedule

The schedule abstract method is the primary method where tasks are defined and scheduled. It uses the service method to register services and allows chaining additional configuration methods such as seconds and output.

protected function schedule(): void

Responsibilities

Define services to be executed by cron.
Set the execution interval for each service.
Specify log file paths for task output.

Example Implementation

protected function schedule(): void
{
    $this->service('\App\Controllers\Cli\ServiceOneCommand::fooMethod')
        ->seconds(5) 
        ->output(root('/writeable/log/') . 'cron-one.log');

    $this->service('\App\Controllers\Cli\ServiceTwoCommand::barMethod')
        ->minutes(10)
        ->log('info');
}

Configuration Options

service

The service method specifies the task to be executed. It accepts a combination of a controller class and a method name. The controller can be an Http controller or a Cli controller class designed for execution.

Usage

The service definition must adhere to the following pattern: a fully qualified class name (FQCN) followed by :: and the method name, resembling the syntax for invoking a static method.

$this->service('\Namespace\Controllers\Cli\Controller::method');

Full Example

Below is a complete example of the Cron class configuration:

// /app/Config/Cron.php
namespace App\Config;

use Luminova\Foundation\CoreCronTasks;

final class Cron extends CoreCronTasks
{
    /**
     * Define and schedule tasks for cron execution.
     */
    protected function schedule(): void
    {
        $this->service('\App\Controllers\Cli\ServiceOneCommand::fooMethod')
            ->seconds(5) 
            ->output(root('/writeable/log/') . 'cron-one.log');

        $this->service('\App\Controllers\Cli\ServiceTwoCommand::barMethod')
            ->minutes(10)
            ->log('info');
    }
}
