This must be the quickest way to get the LAMP stack up and running locally.
Nothing installed locally -> you can run different versions of PHP/MySQL without conflicts.
Database gets created on first startup and persisted in a named volume.
PHP files are in a mapped volume so you can edit without rebuilding the container.

The docker-compose.yml file:

version: "2"
services:
  site:
    image: php:5.6.27-apache   
    volumes:
      - ./site:/var/www/html
    depends_on:
      - mysql
    networks:
      back-tier:        
  mysql:
    image: mysql:5.5
    environment:
      MYSQL_ROOT_PASSWORD: topsecret
      MYSQL_DATABASE: sitedbname
      MYSQL_USER: sitedbuser
      MYSQL_PASSWORD: sitedbpassword
    volumes:
      - site_db:/var/lib/mysql
    networks:
      back-tier:
networks:
  back-tier:
volumes:
  site_db: 

Then just

docker-compose up

It takes a bit of the pain out of working on a legacy PHP site!
