Set Up PHP 8 Environment Using Docker with a Custom Dockerfile

#devops #webdev #php #laravel

You use Docker to run PHP 8 through a custom Dockerfile. This process involves building an image from the Dockerfile, where PHP and necessary extensions are installed, then running a container based on that image to set up a PHP environment ready for development or deployment.
