PHP configuration files (XML versus YAML and PHP files)

Question

Im doing a little experiment. In the old days, most people saved configuration files in a php file as a bunch of constants or a class with the loooot attribute. Now we see projects like symfony using yaml or something else. My question is:

If you can choose one of three ways to store your configuration files: xml, yaml or php files, which would you choose? Most important: why?

thanks for the help

Answer 1

For me, it depends on who will touch this configuration.

If they are developers, then PHP files are best, since they do not require additional analysis.
