Docker PHP MySQL Setup

### Step 1: Create a `docker-compose.yml` file
In your project directory, create a file named `docker-compose.yml` and add the following content:

version: '3.8'

services:
  # Apache and PHP 8 service
  web:
    image: php:8.0-apache
    container_name: php_apache
    volumes:
      - ./src:/var/www/html
    ports:
      - "8080:80"
    networks:
      - app-network
    depends_on:
      - db

  # MySQL service
  db:
    image: mysql:8.0
    container_name: mysql_db
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: my_database
      MYSQL_USER: user
      MYSQL_PASSWORD: password
    volumes:
      - db_data:/var/lib/mysql
    ports:
      - "3306:3306"
    networks:
      - app-network

  # Adminer service
  adminer:
    image: adminer
    container_name: adminer
    depends_on:
      - db
    ports:
      - "8081:8080"
    networks:
      - app-network

networks:
  app-network:
    driver: bridge

volumes:
  db_data:

### Step 2: Directory Structure
Make sure to create the following structure in your project directory:

project-directory/
│
├── src/                  # Place your PHP files here (e.g., index.php)
│
├── docker-compose.yml

### Step 3: Start the Docker Containers
Run the following command to start all the containers:

docker-compose up -d

– **PHP and Apache** will be accessible on `http://localhost:8080`.
– **Adminer** (a web-based MySQL management tool) will be available at `http://localhost:8081`.
– **MySQL** will be running on `localhost:3306`.

### Step 4: Accessing Services
– You can place your PHP files inside the `src` directory.
– Visit `http://localhost:8081` to access Adminer, and use the credentials defined in the `db` service to log in:
– System: `MySQL`
– Server: `db` (because Adminer and MySQL are in the same Docker network)
– Username: `user`
– Password: `password`
– Database: `my_database`

This should give you a complete local development environment for PHP 8, MySQL, Adminer, and Apache using Docker!
