Class Shanchu { All files in the loop directory function Delfileunderdir ($dirName = ": /smarty/templates/templates_c ") { if ($handle = Opendir ("$dirName")) { while (false!== ($item = Readdir ($handle))) { if ($item! = "." && $item! = "...") { if (Is_dir ("$dirName/$item")) { Delfileunderdir ("$dirName/$item"); } else { if (unlink ("$dirName/$item")) echo "successfully deleted file: $dirName/$item n "; } } } Closedir ($handle); } } } ?> Suppose you need to delete all the files in the directory named "Upload" (but without deleting the directory folder), you can do this with the following code: Delfileunderdir (' upload '); ?>
