# 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/).
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:
```
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 && sync && \
install-php-extensions gd xdebug
```
Installation via COPY --from
```
FROM php:7.2-cli
COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/bin/
RUN install-php-extensions gd xdebug
```
`install-php-extensions` will install all the required APT packages.
If you want to remove the APT development packages (which shouldn't be needed after the PHP extensions have been installed) and other no longer required packages, you can use the `--cleanup` option (**EXPERIMENTAL**):
```
install-php-extensions --cleanup gd xdebug
```

<!-- END OF EXTENSIONS TABLE -->
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:
<!-- START OF SPECIAL REQUIREMENTS -->
<!-- ########################################################### -->
<!-- # # -->
<!-- # DO NOT EDIT THIS TABLE: IT IS GENERATED AUTOMATICALLY # -->
<!-- # # -->
<!-- # EDIT THE data/special-requirements FILE INSTEAD # -->
<!-- # # -->
<!-- ########################################################### -->
| Extension | Requirements |
|:---:|:---:|
| parallel | Requires images with PHP compiled with thread-safety enabled (`zts`). |
| pthreads | Requires images with PHP compiled with thread-safety enabled (`zts`). |
<!-- END OF SPECIAL REQUIREMENTS -->
## How to contribute
- If you want to add support for a new PHP extension:
1. change the `install-php-extensions` script
2. update the `data/supported-extensions` file, adding a new line with the handle of the extension and the list of supported PHP versions
3. if the extension requires ZTS images:
add a new line to the `data/special-requirements` file, with the extension handle followed by a space and `zts`
- If you want to change the list of supported PHP versions for an already supported extension:
1. change the `install-php-extensions` script
2. update the `data/supported-extensions` file, adding the new PHP version to the existing line corresponding to the updated extension
- If you change some code that affects one or more extensions, please add a line with `Test: extension1, extension2` to the message of one of the pull request commits.
Here's an example of a commit message:
```
Improve the GD and ZIP extensions
Test: gd, zip
```
