XDEBUG - Ubuntu - INI-hierarchy

Question

I changed my PHP version and also XDebug on Ubuntu 20.04.3 LTS. How could it be otherwise, now the debugging doesn't work anymore. I used xdebug_info() to display the current values for XDebug. Am now at the approach which INI I have to adjust. But no matter in which INIs displayed by xdebug_info().

I enter a value for xdebug.idekey, it doesn't matter?? Which hierarchy do the INIs follow? It's like pinching the horn of an ox.

And of course I restarted Apache.

Unless you're using a DBGp proxy, you don't need to set the IDE Key.

Which hierarchy do the INIs follow?

In the order you see them on that page, with later listed files overriding settings encountered earlier.

But no matter in which INIs displayed by xdebug_info().

You don't actually show any of that in your screenshot, only which files are listed.
