What are design patterns

Design patterns are industry-standard solutions to common software design problems that occur during software development. They define a way to structure code and make it easier to understand, reuse, and maintain. By using design patterns, developers can communicate more effectively, improve code quality, and enhance software design.

Example of a Singleton Design Pattern in PHP

<?php class Singleton { private static $instance; private function __construct() { // Prevent direct object creation } public static function getInstance() { if (!self::$instance) { self::$instance = new Singleton(); } return self::$instance; } } // Usage $instance1 = Singleton::getInstance(); $instance2 = Singleton::getInstance(); echo ($instance1 === $instance2) ? 'Same instance' : 'Different instances'; // Output: Same instance ?>
