Design Patterns in PHP

Welcome to Design Patterns implemented using PHP programming language. Each design pattern is explained with a problem statement, solution, steps to implement, implementation (source code), and when to use. 

Design patterns are typical solutions to common problems in software design. Each pattern is a blueprint that can be customized to solve a particular design challenge in various situations. They provide a shared language and framework for expressing solutions and discussing design alternatives. 

The Gang of Four classifies design patterns into three distinct categories: Creational, Structural, and Behavioral. 

1. Creational Patterns 

These patterns deal with object creation mechanisms, ensuring you create objects in a manner suitable to your situation, while also keeping the system decoupled from specific classes it creates.

2. Structural Patterns 

These patterns concern class and object composition. They allow you to compose structures in a way that you can ensure a change in one place doesn't necessitate changes throughout the system.

3. Behavioral Patterns 

These patterns focus on object collaboration and the delegation of responsibilities among objects.
