Introduction¶

PHP is a server-side scripting language designed primarily for web development but also used as a general-purpose programming language.

Versions¶

Standard version¶

If you don’t select a certain version, our default will be used. We decided to default to version 8.4, which is considered to be stable by the developers.

Available versions¶

We provide versions 8.3 and 8.4

Change version¶

You can select the PHP version with the uberspace tool. You can choose between release branches:

[isabell@stardust ~]$ uberspace tool version set php 8.3
OK: Set version of php to 8.3

How to publish¶

Put your PHP files into your document root. The file extension should be .php. For security reasons we don't parse PHP code in every file.

Configuration¶

Provided configuration¶

Get your configuration via php -i.

Custom configuration¶

You can add custom config files to ~/.config/php/.

For example add a file ~/.config/php/memory_limit.ini with the content:

memory_limit = 512M

To make the changes available for your PHP web service, you need to reload it:

[isabell@moondust ~]$ uberspace web php reload
