Rookie needs help - filtering path?

[HansDampfHH]

Perhaps a slight trouble, but I can not solve it:

 

Match only path like:

Trainings/1/test.pdf

 

but dont match one more directory like this:

Trainings/1/4/other.pdf

 

Any suggestions?

You don't need a regex unless you actually need to match a pattern..

 

<?php if (substr_count($path, '/') > 2) { echo "Directories too deep"; }

How simple, of course.

Thanks a lot for the hint ;-)
