class listdir{
var $depth;
var $dirname;
var $list;
var $tostring;

function listdir($dir){
$this->dirname=$dir;
$this->depth=0;
$this->tostring=”";

//把结果保存进多维数组
function getlist($dir=”"){
if($dir==”")$dir=$this->dirname;
$d=@dir($dir);
while(false!==($item=$d->read()))
{
if($item!=”.”&&$item!=”..”)
{
$path=$dir.”/”.$item;
if(is_dir($path)){
$this->depth+=1;
$this->getlist($path);
}else{
$this->list[$this->depth][]=$item;
