README

A PHP library providing a simple and efficient queue implementation for managing collections of items in a FIFO (First-In-First-Out) manner.

Installation

Install the package via Composer:

composer require vairogs/functions-queue

Requirements

PHP 8.4 or higher

Usage

The Queue class provides a simple implementation of a FIFO (First-In-First-Out) queue data structure.

use Vairogs\Functions\Queue\Queue;

// Create a new Queue instance
$queue = new Queue();

// Add items to the queue
$queue->push(1);
$queue->push(2);
$queue->push(3);

// Check if the queue contains an item
$containsTwo = $queue->contains(2); // true

// Get the number of items in the queue
$count = count($queue); // 3

// Check if the queue is empty
$isEmpty = $queue->isEmpty(); // false

// Get the first item without removing it
$firstItem = $queue->peek(); // 1

// Remove and return the first item
$firstItem = $queue->pop(); // 1

// Clear all items from the queue
$queue->clear();

You can also initialize a queue with an array of items:

// Create a queue with initial items
$queue = new Queue([1, 2, 3]);

// Get the number of items
echo count($queue); // 3
