# Easy installation of PHP extensions in official PHP Docker images

This repository contains a script that can be used to easily install a PHP extension inside the [official PHP Docker images](https://hub.docker.com/_/php/).


## Known limits

Currently the script requires the Debian-based images (no Alpine).


## Usage

Here's a sample Dockerfile that installs the GD and xdedub extensions inside a docker image:

```
FROM php:7.2-cli

ADD https://raw.githubusercontent.com/mlocati/docker-php-extension-installer/master/install-php-extensions /usr/local/bin/

RUN chmod uga+x /usr/local/bin/install-php-extensions && \
    install-php-extensions gd xdebug
```

PS: the pre-installed PHP extensions are excluded from this list.
You can list them with the following command (change `php:7.2-cli` to reflect the PHP version you are interested in):

```sh
docker run --rm -it php:7.2-cli php -m
```

## Special requirements

Some extension has special requirements:
