2x server same PHP code but only working on one

[kuchenmann]

I've two Debian12 servers.
on is on an older physical server HP Prolian N40L and the second virtual on ProxMox.
It's the same Debian12 bookworm and PHP 8.2.7 on both and the same small test.php.
Tested just a simple form with 2 text-fields which are displayed on same page after clicking on submit, but it only works on the virtual server.
On the physical server I see parts of the PHP code, even before clicking submit.
Any suggestions?
Thanks.

After I purged libapache2-mod-php and installed it again, it WORKS!
Thanks
