## What it is
A collection of sample code implementations of well-known software design patterns in PHP 8.x, with explanations and runnable PHPUnit tests. It is accompanied by hosted documentation on Read the Docs available as HTML, PDF, and Epub.

## Use cases
- learn how to implement design patterns in PHP
- see examples of creational, structural, and behavioral patterns
- study modern PHP 8 object-oriented code
- find out which design pattern fits a given problem
- run example pattern code with PHPUnit tests

## When to choose
- you are a PHP developer learning or teaching design patterns
- you want concise, tested reference implementations of classic patterns
- you need modern PHP 8.x code examples for OOP idioms

## When to avoid
- you need a production-ready pattern library to import into your project
- you work in a language other than PHP
- you want exhaustive coverage of every pattern variant or architectural patterns

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation, testing
- domain: developer-tools, tutorials, programming-languages
- platform: php, cross-platform
- tags: design-patterns, oop, php8, code-examples, phpunit
