Description

The PHP 8 container image

PHP is a general-purpose scripting language used primarily for server-side web development. It can be used directly, embedded in HTML files, or executed via a server-side Apache2 module or CGI scripts.

How to use the image

This image ships with the PHP interpreter as the entrypoint. The image is intended to be used to execute PHP scripts or PHP commands directly.

To launch an interactive shell in a container, use the following command:

$ podman run --rm -it registry.suse.com/bci/php:8
Interactive mode enabled

php > echo 5+8;
13

You can also use the container instead of the PHP interpreter to execute PHP scripts:

$ cat /tmp/test.php
<?php
echo 5+8
$ podman run --rm -it -v /tmp/test.php:/src/test.php:Z \
    registry.suse.com/bci/php:8 -f /src/test.php
13

How to install PHP extensions

PHP extensions must be installed using the zypper package manager. PHP extensions are named using the php8-$extension_name scheme, and they can be installed as follows:

FROM registry.suse.com/bci/php:8

RUN zypper -n in php8-gd php8-intl

Alternatively, you can use the docker-php-ext-install script. It is provided for compatibility with the PHP DockerHub Image but it uses zypper to install the extensions from RPMs. It is provided for compatibility reasons and can be used similar to the script from PHP DockerHub image:

FROM registry.suse.com/bci/php:8

RUN docker-php-ext-install gd intl

How to install PECL extensions

PECL is a package repository hosting PHP extensions. It can be used as an alternative source to obtain PHP extensions, but without any guarantee of interoperability with this image and without any official support.

Install PECL extensions as follows:

FROM registry.suse.com/bci/php:8

RUN set -euo pipefail; \
    zypper -n in $PHPIZE_DEPS php8-pecl; \
    pecl install APCu-5.1.21;

Note: Building an extension may require installing its dependencies first.

Compatibility with the DockerHub Image

The following scripts ship with the image to keep it compatible with the DockerHub image: docker-php-source, docker-php-ext-configure, docker-php-ext-enable, and docker-php-ext-install. The script docker-php-ext-install performs an actual job, all others are just no-operation scripts for interoperability.
