How to install PHP 7.4 on SLE 15 SP 4

Hello,

we want to be part of supported OS versions by SUSE.
So we want to use SLES 15 SP4.

Our developers on the other hand want to use actual MediaWiki version which is not supported using PHP 8 (which is shipped in SLES 15 SP4)

How can i fullfill our internal OS supportability with a PHP 7.4 repo?

on this link

sadly there is no Build Flag for SP4.

Does anybody know how to proceed?

SLES 15 SP4 ships with the Legacy Module, which includes some PHP 7.4 RPM packages. Maybe this is sufficient for your use case.
