# 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 -it --rm --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 two convenient scripts named `docker-php-ext-configure` and `docker-php-ext-install`, you can use them to easily install PHP extension.
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:5.6-fpm
# Install modules
RUN apt-get update && apt-get install -y \
libfreetype6-dev \
libjpeg62-turbo-dev \
libmcrypt-dev \
libpng12-dev \
&& docker-php-ext-install iconv mcrypt \
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install gd
CMD ["php-fpm"]
```
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.
### 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 -p 80:80 -it --rm --name my-apache-php-app -v "$PWD":/var/www/html php:5.6-apache
```
