if ($dh = Opendir ($cachedir)) {//Open the cache folder;
while (($file = Readdir ($DH))!== false) {//traverse the cache directory,
Unlink ($cachedir. $file); Delete each file that is traversed;
}
Closedir ($DH);
}
$tempdir = Runtime_path. "/temp/"; The path to the cache file;
if ($dh = Opendir ($tempdir)) {//Open the cache folder;
