Which PHP versions are supported by operating system?
RHEL =
Debian =
Ubuntu =

I don't see this listed anywhere.

I don't see this listed anywhere.

You have to search on Google for that as that is an OS thing, not a DA thing which is why it's not listed here.

And RHEL... which version RHEL? Mostly the OS versions have a way lower version in use than Directadmin is using, because DA is compiling them from source and not using the package manager for PHP.

So a little search on Google brought:
RHEL 8 : php:7.4
A bit looking further brought that RHEL 9 comes with php 8.0.

So you should be able to find the versions you want to know from which distro and distro versions via Google.

I'm glad I asked. For the moment I'll stick with old DA and upgrade the program but the program is immense including non-OO calls to MySQL. There will be plenty of other issues as well with PHP because they removed a lot of defaults that now throw errors instead. Obviously being able to run the older versions of PHP is a severe issue for many otherwise the we wouldn't see the ability to run the older versions in OS repositories. OTOH, cPanel does the same as DA, thus neither of those two support it.

thus neither of those two support it.

Correct, which is a good thing because those older PHP versions are already EOL and also often have security issues.
So the only usable older php versions might be via Cloudlinux because (if I'm informed correctly) they patch the php versions themselve so they don't have those security issues.

As far as I know one can still run php 7.4 or 8.0 on cPanel unless that changed not too long ago, but it does warn that it's a non supported EOL version.

I don't see Cloudlinux on the DA support list so that's out.

 

[Richard G]

Yes it is supported.

However be aware that CL9 is only just released for CP if I'm correct and CL is still working on support for DA and Plesk.
So it's not 100% sure yet if that is 100% supported or some parts will not be, same for Plesk by the way.

Thank you so much for that valuable information.
