Thank you for advice.
My directory structure is:
When I give an exact path it does not load the test.php it gives me an ERR "object not found"
What could be a reason for an exact PATH not to work?
I did not try yet default link as you advised, However, the one I had working was c://localhos/xampp/
and this works only for those PHP files that are located directly in "htdocs" which is a child of "xampp".
