This repository contains a script that can be used to easily install a PHP extension inside the official PHP Docker images.
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:
- Debian-based docker images: since jessie (Debian 8) (minimum PHP version: 5.5)
- Alpine-based docker images: since Alpine 3.9 (minimum PHP version: 7.1)
See also the notes in the Special requirements section.
You have many ways to use this script within your Dockerfile
s.
Here's a list of sample Dockerfile
s that install the GD and xdebug PHP extensions:
FROM php:7.2-cli
ADD --chmod=0755 https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions /usr/local/bin/
RUN install-php-extensions gd xdebug
FROM php:7.2-cli
RUN curl -sSLf \
-o /usr/local/bin/install-php-extensions \
https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions && \
chmod +x /usr/local/bin/install-php-extensions && \
install-php-extensions gd xdebug
FROM php:8.2-cli
RUN curl -sSL https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions -o - | sh -s \
gd xdebug
FROM php:7.2-cli
COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/local/bin/
RUN install-php-extensions gd xdebug
Warning: by using this method you may use an outdated version of the mlocati/php-extension-installer
image.
You may want to run docker pull mlocati/php-extension-installer
in order to use an up-to-date version.
RUN --mount=type=bind,from=mlocati/php-extension-installer:latest,source=/usr/bin/install-php-extensions,target=/usr/local/bin/install-php-extensions \
install-php-extensions gd xdebug
Warning: by using this method you may use an outdated version of the mlocati/php-extension-installer
image.
You may want to run docker pull mlocati/php-extension-installer
in order to use an up-to-date version.
Simply append -<version>
to the module name.
For example:
install-php-extensions xdebug-2.9.7
The script also supports resolving compatible versions by prefixing the version with a caret (^
).
For example:
# Install the most recent xdebug 2.x version (for example 2.9.8)
install-php-extensions xdebug-^2
# Install the most recent xdebug 2.8.x version (for example 2.8.1)
install-php-extensions xdebug-^2.8
Please remark that with the syntax above you'll get the vary latest compatible version, which may be unstable. In order to install the most recent stable version, you can append @stable
:
# Install the most recent STABLE xdebug 3.x version (for example 3.2.2)
install-php-extensions xdebug-^3@stable
(valid suffixes are: @snapshot
, @devel
, @alpha
, @beta
, and @stable
)
Pre-release versions extensions available on PECL
can be setup by suffixing the extension's name with its state i.e. alpha
, beta
, rc
, preview
, devel
or snapshot
.
For example:
install-php-extensions xdebug-beta
TIP: When the latest version available on PECL
is not stable, and you want to keep the last stable version,
force it by suffixing the extension's name with the stable
state.
For example:
install-php-extensions mongodb-stable
You can also install PHP extensions from source code (provided that it comes with a package.xml
or a package2.xml
file).
Accepted formats are:
- A short version for repositories hosted on GitHub.
For example, for the php-memcached-dev/php-memcached GitHub repository, you can simply write:# Install from a specific commit (full commit SHA-1) install-php-extensions php-memcached-dev/php-memcached@8f106564e6bb005ca6100b12ccc89000daafa9d8 # Install from a specific commit (short commit SHA-1) install-php-extensions php-memcached-dev/php-memcached@8f106564e6bb # Install from tag v3.2.0RC2 install-php-extensions php-memcached-dev/[email protected] install-php-extensions php-memcached-dev/php-memcached@refs/tags/v3.2.0RC2 # Install from branch master install-php-extensions php-memcached-dev/php-memcached@master install-php-extensions php-memcached-dev/php-memcached@refs/heads/master
- An URL providing an archive containing the source code.
Examples:# tgz archive for commit 8f106564e6bb005ca6100b12ccc89000daafa9d8 install-php-extensions https://codeload.github.com/php-memcached-dev/php-memcached/tar.gz/8f106564e6bb005ca6100b12ccc89000daafa9d8 # tgz archive for tag v3.1.5 install-php-extensions https://codeload.github.com/php-memcached-dev/php-memcached/tar.gz/refs/tags/v3.1.5 # tgz archive for branch master install-php-extensions https://codeload.github.com/php-memcached-dev/php-memcached/tar.gz/refs/heads/master
- The absolute path of a local directory.
Examples:# Download the source code curl -o /tmp/source.tgz https://codeload.github.com/php-memcached-dev/php-memcached/tar.gz/refs/tags/v3.1.5 tar xzf /tmp/source.tgz -C /tmp install-php-extensions /tmp/php-memcached-3.1.5
You can also install composer, and you also can specify a major version of it, or a full version.
Examples:
# Install the latest version
install-php-extensions @composer
# Install the latest 1.x version
install-php-extensions @composer-1
# Install a specific version
install-php-extensions @composer-2.0.2
The root CA certificate of Let's Encrypt changes (more details here).
That breaks old linux distributions, namely:
- Debian Jessie (8)
- Debian Stretch (9)
- Alpine Linux 3.7
- Alpine Linux 3.8
This script can fix this issue: simply pass @fix_letsencrypt
as an argument:
install-php-extensions @fix_letsencrypt

Number of supported extensions: 144
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):
$ docker run --rm php:7.2-cli php -m

You can configure the behavior of the script, as well as fine-tune some extensions in order fit your needs, by using environment variables.
Here's an example:
IPE_LZF_BETTERCOMPRESSION=1 install-php-extensions lzf
Here's the list of all the supported environment variables:
Extension | Environment variable | Description |
---|---|---|
IPE_DEBUG=1 |
By setting this environment variable, the script will print all the commands it executes (it will be very verbose, useful only for debug purposes) | |
IPE_PROCESSOR_COUNT |
By default all available processors. Set this environment variable to override the number of processors detected by the script (used for parallel compilation) | |
IPE_DONT_ENABLE=1 |
By default the script will install and enable the extensions. If you want to only install them (without enabling them) you can set this environment variable. To enable the extensions at a later time you can execute the command docker-php-ext-enable-<extension> (for example: docker-php-ext-enable-xdebug ).Beware: installing some PHP extensions requires that other PHP extensions are already enabled, so use this feature wisely. |
|
IPE_KEEP_SYSPKG_CACHE=1 |
By default the script will clear the apt/apk/pear cache in order to save disk space. You can disable it by setting this environment variable | |
lzf | IPE_LZF_BETTERCOMPRESSION=1 |
By default install-php-extensions compiles the lzf extension to prefer speed over size; you can use this environment variable to compile it preferring size over speed |
event | IPE_EVENT_NAMESPACE= ... |
By default, the event classes are defined in the root namespace. You can use this environment variable to specify a custom namespace |
gd | IPE_GD_WITHOUTAVIF=1 |
Since PHP 8.1, gd supports the AVIF format. Enabling it requires compiling libaom/libdav1d/libyuv/libavif on Debian 11- and Alpine 3.14-, which is time-consuming. You can disable AVIF support by setting this environment variable on Debian 11- and Alpine 3.14- |
oci8 & pdo_oci | IPE_INSTANTCLIENT_BASIC=1 |
The oci8 and pdo_oci PHP extensions require Oracle Instant Client. In order to save disk space, we install the Basic Lite version: if you want to install the Basic (non-lite) version simply set this environment variable |
http, intl, mongodb | IPE_ICU_EN_ONLY=1 |
Some extensions require the ICU library, use this flag to install a smaller, but English-only, ICU library on Alpine 3.16 and later |
pspell | IPE_ASPELL_LANGUAGES='...' |
Configure the languages to be made available (for example: IPE_ASPELL_LANGUAGES='en fr' ). If omitted, we'll assume en |
IPE_DEB_ARCHIVE & IPE_DEB_ARCHIVE_SECURITY |
The APT packages of very old Debian versions (eg Jessie) may have been archived: you can use these environment variables to specify custom URLs of these APT archives |
Some extensions have special requirements:
You can run this command:
cat /etc/os-release
For example:
- for Debian 11 (Bullseye) you'll see:
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
- for Alpine Linux 3.14 you'll see:
PRETTY_NAME="Alpine Linux v3.14"
When submitting a pull request, a GitHub Action is executed to check if affected PHP extensions actually work (see below).
Furthermore, we also check that new versions of extensions in the PECL repository will still work.
This is done on a scheduled basis with another GitHub Action.
In case of failure, a message is sent to a Telegram Channel.
Feel free to subscribe to it to receive failure notifications.
Before submitting any pull request, you should execute the lint
script in the scripts
directory (or lint.bat
on Windows).
If you don't do that, and if there's a coding style error, you'll see that the Check shell coding style
and/or the Check PHP coding style
GitHub Actions will fail.
The error will be something like this:
--- filename.orig
+++ filename

good line of code #3
- the original line with a wrong coding style
+ the line wrong coding style that has been corrected
good line of code #4

good line of code #6
So, you should fix highlighted line (the one(s) at line number
) by replacing what you see after the -
with what you see after the +
- change the
install-php-extensions
script - update the
data/supported-extensions
file, adding a new line with the handle of the extension and the list of supported PHP versions - if the extension requires ZTS images:
add a new line to thedata/special-requirements
file, with the extension handle followed by a space andzts
See this pull request for an example.
- change the
install-php-extensions
script - update the
data/supported-extensions
file, adding the new PHP version to the existing line corresponding to the updated extension
See this pull request for an example.
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 for an example.
PHP extensions published on the PECL archive contain a package.xml
(or package2.xml
) file describing the supported PHP versions and the options that can be used to compile it.
When we add support for a new PHP extension, and when a new version of a PHP extension is released, we have to check those constraints.
It's a rather tedious task, so I developed a project that lets you easily check those constraints: you can find it at https://mlocati.github.io/pecl-info (here you can find its source code).
See the MAINTAINERS.md
file.
