$filesize = array ();
$filepath = iconv('gb2312', 'utf-8', $fpath);
if (is_dir($fpath)) {
if ($dh = opendir($fpath)) {
while (( $file = readdir($dh)) !== false) {
if($file != '.' && $file != '..') {
$filesize[] = delFile($fpath.'/' .$file);
}

n";
}
} else {

function getArrSum(& $arr) {
if(is_array($arr)) {
foreach ($arr as &$value) {
$value = getArrSum($value);
}
return array_sum($arr);
} else {
return $arr;
}
