System requirements for PHP are confusing (8.0 vs. 8.1)

[froschdesign]

Q	A
Bug?	maybe
New Feature?	no
Sulu Version	2.5.x / latest
Browser Version	irrelevant

Actual Behavior

The skeleton requires PHP version 8.1 and higher:

skeleton/composer.json

Lines 29 to 30 in eb5158c

	"require": {
	"php": "^8.1",

Sulu itself allows version 8.0 and higher:

https://github.com/sulu/sulu/blob/097a23c376f1fddbcdfdbd4f564f7847ec0cc934/composer.json#L27-L28

The documentation says PHP 8.0 and higher:

The following requirements must be met to run Sulu:

• Mac OSX, Linux or Windows
• Apache or Nginx with enabled URL rewriting
• PHP 8.0 or higher
• …

https://docs.sulu.io/en/2.5/reference/requirements.html

Expected Behavior

If Sulu allows version 8 of PHP and the documentation also lists this version under the system requirements, then the skeleton should allow the same version.

Steps to Reproduce

See above.

Possible Solutions

Update the Composer configuration of this package.

Thank you for the feedback.

Why sulu/sulu still supports PHP 8.0. The skeleton and new installation is shipped with latest Symfony Version which requires atleast PHP 8.1. So at current state you can use PHP 8.0 to run latest version of Sulu and old projects on PHP 8 can update to that latest version, but you can not start a new project based on the skeleton because Symfony 6.1 (6.2 is used in 2.5 skeleton) requires now PHP 8.1: https://symfony.com/blog/symfony-6-1-will-require-php-8-1

So looking here I think we should update the docs to set the requirement to PHP 8.1 there for Sulu 2.5. Do you want to create a pull request for it?

I found another notice:

✅  Requirements

Sulu requires a PHP version higher or equal to 8.0 and is compatible with every Symfony version starting from 5.4. Have a look at the require section in the composer.json of the sulu/sulu core framework to find an up-to-date list of the requirements of Sulu content management system.

Okay, that explains it, but it's not clear when you read the documentation, because it says version 8.0 and refers to the skeleton.

Do you want to create a pull request for it?

I will create a pull request on https://github.com/sulu/sulu-docs

Yeah think change the docs that requirement is PHP 8.1 make sense as people reading that are mostly the ones which starting a new project and not working on an existing one.
