php install and manage multiple versions

In https://docs.debops.org/en/master/ansible/roles/php/getting-started.html

is written:

The debops.php role supports management of multiple PHP versions; only one PHP version can be managed at a time.

Does this mean: it can manage different versions or does it mean it's supporting different versions installed at the same time?

We want to achieve multiple running php-versions side by side (8.0, 8.1, 8.2). Is this possible on principle? If had the following list:

php__version_preference: [ 'php8.2', 'php8.1', 'php8.0', 'php7.4' ]

and set

php__reset: True

it does remove all php versions prior to php8.2. If I have set php__reset to False and e.g. php8.0 and php7.4 is installed nothing happend at all.

I guess: the role doesn't support this and the "management of multiple PHP versions" means: you can manage "any" php version but not multiple side by side. Is this right?

Is there any way to achieve a server with multiple php-versions running parallel?

Start with the linked debops.php getting-started documentation and inspect how php__version_preference and php__reset are handled. Verify whether multiple PHP versions can run side by side, using the reported 8.0, 8.1, 8.2, and 7.4 configuration as the case to check. Done means the documentation clearly explains the supported behavior and any configuration limitations.
