What is PHP?

PHP is a server-side scripting language designed for web development, but which can also be used as a general-purpose programming language. PHP can be added to straight HTML or it can be used with a variety of templating engines and web frameworks. PHP code is usually processed by an interpreter, which is either implemented as a native module on the web-server or as a common gateway interface (CGI).

How to use this image.

With Command Line

For PHP projects run through the command line interface (CLI), you can do the following.

Create a Dockerfile in your PHP project

FROM php:5.6-cli
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
CMD [ "php", "./your-script.php" ]

Then, run the commands to build and run the Docker image:

docker build -t my-php-app .
docker run -it --rm --name my-running-app my-php-app

Run a single PHP script

For many simple, single file projects, you may find it inconvenient to write a complete Dockerfile. In such cases, you can run a PHP script by using the PHP Docker image directly:

docker run -it --rm --name my-running-script -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp php:5.6-cli php your-script.php

With Apache

More commonly, you will probably want to run PHP in conjunction with Apache httpd. Conveniently, there's a version of the PHP container that's packaged with the Apache web server.

Create a Dockerfile in your PHP project

FROM php:5.6-apache
COPY . /var/www/html

Then, run the commands to build and run the Docker image:

docker build -t my-php-app .
docker run -it --rm --name my-running-app my-php-app

Without a Dockerfile

If you don't want to include a Dockerfile in your project, it is sufficient to do the following:

docker run -it --rm --name my-apache-php-app -v "$(pwd)":/var/www/html php:5.6-apache
