Setting up our PHP development container

We will need a development environment for our PHP application. We will be separating our development environment structure into two main parts: the Docker container (server) and the PHP application.

The docker directory will contain the following:

• Dockerfile
• docker-compose.yml
• Server configurations

The codebase directory will serve as the following:

• The root directory for our PHP application
• Vendor directory for composer packages

Now, let us set up our PHP development container:

1. Create the following directory structure in your machine:

2. Run the following commands:

   $ mkdir -p ~/phptdd/docker

   $ mkdir -p ~/phptdd/codebase

3. Install Docker Desktop. Before we create the required Docker files, we will need to download and install Docker Desktop.

For macOS users, Docker can be downloaded from https://docs.docker.com/desktop...
