This is silly, I did the parsing engine, the locate, straight forward. However, I have no idea what I am supposed to do for indexes. Yes, I read the instructions but they make no sense.
"that the function, given a /path/to/a/directory, returns /path/to/a/directory/index.php if index.php actually exists therein,"
Well, if it exist already, what am I to do...???
I know, silly, probably not seeing the forest for the trees but.....
