FROM php:8.2-cli

🚀 Quick Start

Basic Queue Operations

<?php

// Create queue instance
$queue = new KislayQueue();

// Enqueue messages
$queue->enqueue('user_notifications', [
    'user_id' => 123,
    'type' => 'email',
    'template' => 'welcome',
    'data' => ['name' => 'John Doe']
]);

$queue->enqueue('order_processing', [
    'order_id' => 'ORD-001',
    'action' => 'process_payment',
    'amount' => 99.99
]);

// Dequeue messages
$message = $queue->dequeue('user_notifications');
if ($message) {
    processNotification($message);
    $queue->acknowledge($message['id']);
}

// Get queue statistics
$stats = $queue->getStats('user_notifications');
echo "Queue size: {$stats['size']}\n";
echo "Processing rate: {$stats['rate']}/sec\n";

Message Priorities and TTL

<?php

$queue = new KislayQueue();

// High priority message
$queue->enqueue('urgent_tasks', [
    'task' => 'security_alert',
    'priority' => 10,
    'ttl' => 3600  // 1 hour
]);

// Delayed message
$queue->enqueue('scheduled_tasks', [
    'task' => 'monthly_report',
    'delay' => 86400  // 24 hours
]);

Pub/Sub Pattern

<?php

$queue = new KislayQueue();

// Publisher
$queue->publish('user_events', [
    'event' => 'user_registered',
    'user_id' => 123,
    'timestamp' => time()
]);

// Subscriber
$subscription = $queue->subscribe('user_events');
while ($message = $subscription->getMessage()) {
    handleUserEvent($message);
    $subscription->acknowledge($message['id']);
}

Backend Integration

<?php

$queue = new KislayQueue();

// Redis backend
$redis = new RedisQueue([
    'host' => 'redis-server',
    'port' => 6379,
    'password' => 'secret',
    'database' => 1
]);
$queue->setBackend($redis);

// RabbitMQ backend
$rabbitmq = new RabbitMQQueue([
    'host' => 'rabbitmq-server',
    'port' => 5672,
    'username' => 'guest',
    'password' => 'guest',
    'vhost' => '/',
    'exchange' => 'kislay_exchange'
]);
$queue->setBackend($rabbitmq);

// Kafka backend
$kafka = new KafkaQueue([
    'brokers' => ['kafka-1:9092', 'kafka-2:9092'],
    'group_id' => 'kislay-consumers',
    'topic_prefix' => 'kislay-'
]);
$queue->setBackend($kafka);

Batch Processing

<?php

$queue = new KislayQueue();

// Enqueue multiple messages at once
$messages = [
    ['queue' => 'batch_jobs', 'data' => ['task' => 'job1']],
    ['queue' => 'batch_jobs', 'data' => ['task' => 'job2']],
    ['queue' => 'batch_jobs', 'data' => ['task' => 'job3']]
];
$queue->enqueueBatch($messages);

// Dequeue multiple messages
$batch = $queue->dequeueBatch('batch_jobs', 10);
foreach ($batch as $message) {
    processJob($message);
}
$queue->acknowledgeBatch(array_column($batch, 'id'));

Error Handling and Retry

<?php

$queue = new KislayQueue([
    'retry_policy' => [
        'max_attempts' => 3,
        'backoff' => 'exponential',
        'initial_delay' => 1000,  // ms
        'max_delay' => 30000      // ms
    ],
    'dead_letter_queue' => 'failed_jobs'
]);

try {
    $message = $queue->dequeue('processing_queue');
    processMessage($message);
    $queue->acknowledge($message['id']);
} catch (Exception $e) {
    // Message will be retried automatically
    $queue->nacknowledge($message['id'], $e->getMessage());
}
