Getting Started

Requirements​

PHP 8.3 or higher

Installation​

Install the package via Composer:

composer require "byjg/singleton-pattern"

This package has no external dependencies - just one trait and one exception class.

What is the Singleton Pattern?​

The Singleton pattern is a design pattern that restricts the instantiation of a class to a single instance. This is useful when exactly one object is needed to coordinate actions across the system.

Quick Example​

<?php
require "vendor/autoload.php";

class MyConfig
{
    use \ByJG\DesignPattern\Singleton;

    private function __construct()
    {
        // Load configuration
    }
}

// Get the single instance
$config = MyConfig::getInstance();
