# 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

```dockerfile
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:

```console
$ 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:

```console
$ 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

```dockerfile
FROM php:5.6-apache
COPY src/ /var/www/html/
```

Where `src/` is the directory containing all your php code. Then, run the commands to build and run the Docker image:

```console
$ docker build -t my-php-app .
$ docker run -d --name my-running-app my-php-app
```

We recommend that you add a custom `php.ini` configuration. `COPY` it into `/usr/local/etc/php` by adding one more line to the Dockerfile above and running the same commands to build and run:

```dockerfile
FROM php:5.6-apache
COPY config/php.ini /usr/local/etc/php/
COPY src/ /var/www/html/
```

Where `src/` is the directory containing all your php code and `config/` contains your `php.ini` file.

### How to install more PHP extensions

We provide the helper scripts `docker-php-ext-configure`, `docker-php-ext-install`, and `docker-php-ext-enable` to more easily install PHP extensions.

#### PHP Core Extensions

For example, if you want to have a PHP-FPM image with `iconv`, `mcrypt` and `gd` extensions, you can inherit the base image that you like, and write your own `Dockerfile` like this:

```dockerfile
FROM php:5-fpm
RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libmcrypt-dev \
        libpng12-dev \
    && docker-php-ext-install -j$(nproc) iconv mcrypt \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install -j$(nproc) gd
```

Remember, you must install dependencies for your extensions manually. If an extension needs custom `configure` arguments, you can use the `docker-php-ext-configure` script like this example.

#### PECL extensions

Some extensions are not provided with the PHP source, but are instead available through [PECL](https://pecl.php.net/). To install a PECL extension, use `pecl install` to download and compile it, then use `docker-php-ext-enable` to enable it:

```dockerfile
FROM php:5-fpm
RUN apt-get update && apt-get install -y libmemcached-dev \
	&& pecl install memcached \
	&& docker-php-ext-enable memcached
```

#### Other extensions

Some extensions are not provided via either Core or PECL; these can be installed too, although the process is less automated:

```dockerfile
FROM php:5-apache
RUN curl -fsSL 'https://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz' -o xcache.tar.gz \
    && mkdir -p xcache \
    && tar -xf xcache.tar.gz -C xcache --strip-components=1 \
    && rm xcache.tar.gz \
    && ( \
        cd xcache \
        && phpize \
        && ./configure --enable-xcache \
        && make -j$(nproc) \
        && make install \
    ) \
    && rm -r xcache \
    && docker-php-ext-enable xcache
```

### Without a `Dockerfile`

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

```console
$ docker run -d -p 80:80 --name my-apache-php-app -v "$PWD":/var/www/html php:5.6-apache
```

# Image Variants

The `php` images come in many flavors, each designed for a specific use case.

## `php:<version>`

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.

## `php:alpine`

This image is based on the popular [Alpine Linux project](http://alpinelinux.org), available in [the `alpine` official image](https://hub.docker.com/_/alpine). Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.

This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use [musl libc](http://www.musl-libc.org) instead of [glibc and friends](http://www.etalabs.net/compare_libcs.html), so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See [this Hacker News comment thread](https://news.ycombinator.com/item?id=10782897) for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.

To minimize image size, it's uncommon for additional related tools (such as `git` or `bash`) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the [`alpine` image description](https://hub.docker.com/_/alpine/) for examples of how to install packages if you are unfamiliar).
