The manual says that one should only call closedir with a parameter which is an open directory handle.



The manual usually lists warnings and errors generated by violating a "should" or "shouldn't", but doesn't for this case.



In fact, one gets the runtime error

   Warning: closedir(): supplied argument is not a valid Directory resource in whatever.php on line nn

irrespective of whether it's an already-closed directory handle or whether it's total junk.



[Different error messages would have spared me a little debugging. Sigh. It would be nice if the manual said.]

About deleting a directory after doing a readdir/closedir on it... I'm not sure if this is the solution, but you could try to chdir("/"); before the rmdir to make absolutely sure you aren't standing in the directory (i.e trying to pull out the rug from under yourself).
