IcePHP/MiniQueue is a lightweight PHP library for managing job queues and processing tasks asynchronously. This library provides a simple and efficient way to handle tasks in the background, allowing your application to perform time-consuming operations without blocking the main execution flow.

Usage

• Include the MiniQueue library in your project.
• Use the provided classes and methods for managing job queues and processing tasks.
• See examples in the code for sending scheduled emails and processing jobs.

Getting Started

Installation

To get started, include the MiniQueue library in your project:

$miniQueue = require_once __DIR__."/queue.php";
require __DIR__ . '/vendor/autoload.php';
use IcePHP\MiniQueue\MiniQueue, IcePHP\MiniQueue\ORM\Job;

Examples

Sending Scheduled Emails

$emailSender = new EmailSender();

$emailData = [
    // ...
];

$emailSender->sendScheduledEmail($emailData);

Running the Worker

You can run the worker using a cron job:

* * * * * /usr/local/bin/ea-php81 /home/****/public_html/****/worker.php

Make sure to adjust the path to the PHP executable (/usr/local/bin/ea-php81) and the path to your worker.php script accordingly.
