Learn how to implement the most important Design Patterns into your PHP application. This project uses PHP 8+. it has examples for each Pattern and an Article explaining how to use them step by step, their advantages, and disadvantages.

Every week a new Pattern + Article on www.medium.com/@anhaia.gabriel and www.medium.com/devwarlocks

PHP 8.2+ - Design Patterns

This repository was created to show the implementation of various Design Patterns using PHP 8.2. There is no dependency on a framework, and the examples are the most real as possible based on my own experiences solving real-life problems. Applying the design pattern and its concept in any PHP project will be effortless once you learn the design pattern and its concept.

Dependencies

• Docker

Running the project

I strongly recommend that you follow the articles (links above) and run them with Docker. It will be much easier, and you need to install Docker on your computer, independent of the OS you are using. With a few commands, you will run/test all the Design Patterns implemented throughout the course.

1. Build the container:

docker build -t design-patterns .

or if you prefer

make build

2. Run the following commands to test the design patterns:

make help

and then you will see the list of commands

3. You need to run the command with the pattern you want to test, for example:

make strategy

4. In case you want to see a short description of the pattern, you can run the make PATTERN_NAME-help, for example:

make strategy-help

With that, you should see a one-line description of the pattern.

Additional Information

• If you take a look at the examples in the blog or inside the folders /src/{$pattern_name}/ you will notice that almost All the examples contain a folder called components; those folders are the files/classes used to demonstrate how to use each pattern. Never consider what is in there as part of the pattern! They are not examples to be followed in your applications.
