I tried editing the PHP configuration via the web interface, and noticed that it shows and applies the same configuration (in my case, the one from the oldest version) to all other PHP versions. Is php.ini guaranteed to be forwards and backwards compatible like that?
I looked at the differences briefly, and it looked okay, but I might want to use the configuration from my newest version instead. I noticed short tags is enabled in 8.2 for some reason, but saving the configuration here would then disable them again via the 7.4 configuration. I wanted to edit disable_functions, and noticed that 7.4 has a long list of functions listed, where newer versions has none.
I can edit them via the file system if necessary, but as I said, editing it via the admin panel seems to pick one of the versions (arbitrarily?) and then copy that configuration to all the other versions, which seems a little dangerous.
I would expect that the feature either be disabled, let me pick which version to edit, or edit perhaps the system default version and not copy the configuration to the other versions.
