I can see what you are trying to do however it's not going to work
the way you have it. Sure its static var but its going to change every
time it you recursivly call blah (due to this line $baseDir = $item; &
this line if (is_dir("$baseDir/$fyl")) blah($item); );
(e.g. everytime it finds a dir its going to change the value of
baseDir).
