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/).
The script will install all the required APT/APK packages; at the end of the script execution, the no-more needed packages will be removed so that the image will be much smaller.
The script works both for Alpine and Debian Linux.
## Usage
Here's a sample Dockerfile that installs the GD and xdedub extensions inside a docker image:
You have two ways to use this script within your `Dockerfile`s: you can download the script on the fly, or you can grab it from the [`mlocati/php-extension-installer` Docker Hub image](https://hub.docker.com/r/mlocati/php-extension-installer).
With the first method you are sure you'll always get the very latest version of the script, with the second method the process is faster since you'll use a local image.
```
For example, here are two `Dockerfile`s that install the GD and xdebug PHP extensions:
### Downloading the script on the fly
```Dockerfile
FROM php:7.2-cli
ADD https://raw.githubusercontent.com/mlocati/docker-php-extension-installer/master/install-php-extensions /usr/local/bin/

`install-php-extensions` will install all the required APT/APK packages; at the end of the script execution, the no-more needed packages will be removed.
