Thanks for the feedback, Jordi. I appreciate it.
A couple of thoughts upon reading your reply:
Unless I'm missing something, I don't see the problem of having PHP
return that information, since it already does so. E.g. __DIR__ will
return:
/home/username/path/to/dir
so my proposal is not asking for anything new — just to return a partial
string of the path already available from PHP.
Perhaps a magic constant would be the wrong way to do it, but in my
thinking, it would fit right in with __FILE__, __DIR__, etc.
