$dir  =  "/etc/php5/" ;

 // Open a known directory, read directory into variable and then close

         $directory  =  readdir ( $dh );

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).
