How do I use queues

Queues are a fundamental data structure used in programming for managing data in a first-in-first-out (FIFO) order. They allow for efficient processing of tasks and are particularly useful in scenarios like task scheduling, resource sharing, and managing asynchronous data. In PHP, you can implement a queue using various methods, including arrays and the SPL data structures.

Here's a simple example demonstrating how to use a queue in PHP:

<?php // Create a new queue using SPLQueue $queue = new SplQueue(); // Enqueue elements $queue->enqueue("First Task"); $queue->enqueue("Second Task"); $queue->enqueue("Third Task"); // Process items in the queue while (!$queue->isEmpty()) { echo $queue->dequeue() . "<br>"; } ?>
