InitPHP Queue

This library offers performance and asynchrony by queuing your jobs to be done later.

composer require initphp/queue

Create Job

First, start by creating the business class. You can find a simple example below.

require_once __DIR__ . DIRECTORY_SEPARATOR . 'vendor/autoload.php';

namespace App\Jobs;

use InitPHP\Queue\Job;

class MailJob extends Job
{
    protected string $channel = 'mailChannel';
    
    protected string $queue = 'mailQueue';
    
    public function handle(): bool
    {
        $payload = $this->getPayload();
        try {
            if (mail($payload['to'], $payload['subject'])) {
                return true;
            } else {
                return false;;
            }
        } catch (\Throwable $e) {
            return false;
        }
    }
}

Use the push() method to add jobs to the queue;

require_once __DIR__ . DIRECTORY_SEPARATOR . 'vendor/autoload.php';
$adapter = new \InitPHP\Queue\Adapters\RabbitMQAdapter('127.0.0.1', 5267, 'guest', 'guest');

$job = new App\Jobs\MailJob($adapter);

// Add Queue Job
$job->push([
    'to'        => '[email protected]',
    'subject'   => 'Subject Mail',
]);

Write your code to handle the jobs in the queue.

consumer.php

require_once __DIR__ . DIRECTORY_SEPARATOR . 'vendor/autoload.php';
$adapter = new \InitPHP\Queue\Adapters\RabbitMQAdapter('127.0.0.1', 5267, 'guest', 'guest');

$adapter->handle('mailChannel', 'mailQueue');

$adapter->close();

Trigger your consumer code.

php consumer.php

Adapters

• PDO (Database) Adapter
• RabbitMQ Adapter
• Kafka Adapter

PDO Adapter

• PDO Extension

To initialize the PDO adapter, you need a PDO object and 2 tables.

$pdo = new PDO('mysql:host=localhost;port=3307;dbname=queue_db', 'root', 'root');
$adapter = new \InitPHP\Queue\Adapters\PDOAdapter($pdo, 'queue');

The first of these tables is used for those waiting in line and the other for jobs that have errors. The table name into which the failed jobs fall is obtained by adding "_failed" as a suffix to the main table name. Accordingly, create your queue tables using the following SQL.

CREATE TABLE `queue` (
        `id` BIGINT UNSIGNED NOT NULL AUTO_INCREMENT,
        `channel` VARCHAR(255) NOT NULL,
        `queue` VARCHAR(255) NOT NULL,
        `payload` TEXT NULL DEFAULT NULL,
        `created_at` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
        `updated_at` DATETIME NULL DEFAULT NULL,
        `status` TINYINT(1) NOT NULL DEFAULT '0',
        PRIMARY KEY (`id`)
) ENGINE=InnoDB CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE INDEX `channel_queue` ON `queue` (`channel`, `queue`);

CREATE TABLE `queue_failed` (
        `id` BIGINT UNSIGNED NOT NULL AUTO_INCREMENT,
        `queue_id` BIGINT UNSIGNED NOT NULL,
        `channel` VARCHAR(255) NOT NULL,
        `queue` VARCHAR(255) NOT NULL,
        `payload` TEXT NULL DEFAULT NULL,
        `created_at` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
        `updated_at` DATETIME NULL DEFAULT NULL,
        `status` TINYINT(1) NOT NULL DEFAULT '0',
        PRIMARY KEY (`id`)
) ENGINE=InnoDB CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

RabbitMQ Adapter

• RabbitMQ Server
• "php-amqplib/php-amqplib" Library

composer require php-amqplib/php-amqplib

$adapter = new \InitPHP\Queue\Adapters\RabbitMQAdapter('127.0.0.1', 5267, 'guest', 'guest');
