# 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:
|
|
```ShellSession
|
|
$ podman run --rm -it registry.opensuse.org/opensuse/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:
|
|
```ShellSession
|
|
$ cat /tmp/test.php
|
|
<?php
|
|
echo 5+8
|
|
$ podman run --rm -it -v /tmp/test.php:/src/test.php:Z \
|
|
registry.opensuse.org/opensuse/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:
|
|
|
|
```Dockerfile
|
|
FROM registry.opensuse.org/opensuse/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](https://hub.docker.com/_/php)
|
|
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:
|
|
|
|
```Dockerfile
|
|
FROM registry.opensuse.org/opensuse/bci/php:8
|
|
|
|
RUN docker-php-ext-install gd intl
|
|
```
|
|
|
|
## How to install PECL extensions
|
|
|
|
[PECL](https://pecl.php.net/) 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.
|
|
|
|
PECL extensions can be installed as follows:
|
|
|
|
```Dockerfile
|
|
FROM registry.opensuse.org/opensuse/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 additional dependencies.
|
|
|
|
|
|
## 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`. Note that only
|
|
`docker-php-ext-install` performs an actual job. None of the other scripts
|
|
require to be executed in the image.
