<h3>Eliminate the "Works on My Machine" Problem</h3><p>Setting up local development environments using XAMPP or MAMP can lead to deployment issues when the production server has different PHP versions or extension settings. Docker resolves this by packaging your app and dependencies into a lightweight container.</p><h3>1. Writing the Dockerfile</h3><p>Create a `Dockerfile` in your project root. Base your container on an official PHP-Apache image (e.g., `php:8.1-apache`). Write commands to enable rewrite modules, install PDO extensions, and copy your code into the container's `/var/www/html/` directory.</p><h3>2. Defining Services with Docker Compose</h3><p>Use a `docker-compose.yml` file to orchestrate multiple containers. Define one service for your PHP application container and another service for the MySQL database container. Specify environment variables for database credentials and mount volumes to sync local files in real-time.</p><h3>3. Continuous Deployment Benefits</h3><p>Since your Docker container holds its exact PHP configurations and dependency modules, you can deploy the exact same image to hosting platforms like AWS, DigitalOcean, or Heroku, guaranteeing identical performance states.</p>
