php下需要删除多级目录的朋友及可以参考下面的类

<?
//删除目录
class del_path
{
function wm_chief_delpath($del_path)
{
if(!file_exists($del_path))//目标目录不存在则建立
{echo"目录不存在";return false;}
$hand=opendir($del_path);
$i=0;
while($file=readdir($hand))
{$i ;
if($i==1||$i==2)
{continue;}
if(!(strchr($file,".")))
{
$del_s_path=$del_path."/".$file;
$this->wm_chief_delpath($del_s_path);
}
else
{
$del_file=$del_path."/".$file;
$this->wm_chief_file($del_file);
}
}
closedir($hand);
$this->wm_chief_path($del_path);
return true;
}
//删除文件
function wm_chief_file($del_file)
{
unlink($del_file);
}
//删除目录
function wm_chief_path($del_path)
{
rmdir($del_path);
}
}
$DelPath="DelPath";//要删除的目录
$wm_chief=new del_path();
$wm_chief_ok=$wm_chief->wm_chief_delpath($DelPath);
if($wm_chief_ok)
{
echo"删除完毕";
}
?>
