# 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 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.
|
|
|
|
Supported docker images are all the Alpine/Debian versions, except for PHP 5.5 where we only support Debian 8 (jessie) (that is, `php:5.5`, `php:5.5-apache`, `php:5.5-cli`, `php:5.5-fpm`, `php:5.5-zts`)
|
|
|
|
|
|
## Usage
|
|
|
|
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/
|
|
|
|
RUN chmod uga+x /usr/local/bin/install-php-extensions && sync && \
|
|
install-php-extensions gd xdebug
|
|
```
|
|
|
|
### Copying the script from a Docker image
|
|
|
|
```Dockerfile
|
|
FROM php:7.2-cli
|
|
|
|
COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/bin/
|
|
|
|
RUN 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:

## How to contribute
|
|
|
|
### Formatting code
|
|
|
|
Before submitting any pull request, be sure to execute the `lint` script in the `scripts` directory (or `lint.bat` on Windows).
|
|
|
|
### Adding support to 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`
|
|
|
|
See [this pull request](https://github.com/mlocati/docker-php-extension-installer/pull/60) for an example.
|
|
|
|
### Changing the supported PHP versions for an already supported PHP 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
|
|
|
|
See [this pull request](https://github.com/mlocati/docker-php-extension-installer/pull/62) for an example.
|
|
|
|
### Improving code for an already supported 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.
|
|
That way, the test jobs will check the extension even if you don't touch the `data/supported-extensions` file.
|
|
|
|
Here's an example of a commit message:
|
|
|
|
```
|
|
Improve the GD and ZIP extensions
|
|
|
|
Test: gd, zip
|
|
```
|
|
|
|
Tests only check the installation of a single PHP extension at a time.
|
|
If you want to test installing more PHP extensions at the same time, use a commit message like this:
|
|
|
|
```
|
|
Improve the GD and ZIP extensions
|
|
|
|
Test: gd+zip
|
|
```
|
|
|
|
|
|
If your pull request contains multiple commits, we'll check the "Test:" message of every commit.
|
|
If you want to stop parsing next commits, add `-STOP-` in the "Test:" line, for example:
|
|
|
|
```
|
|
Improve the GD and ZIP extensions
|
|
|
|
Test: gd, zip, -STOP-
|
|
```
|
|
|
|
See [this pull request](https://github.com/mlocati/docker-php-extension-installer/pull/43) for an example.
