php小白求救,php关于directory类的错误 Undefined property: Directory::$uu
本人php新手,学电子的想学点网页编程转行做电子商务网站开发。今年大四很迷茫呀,现在兼职开淘宝赚个三四百一个月。好了,转入正题。
  代码如下,我是照书本写的,想测试一下加深理解,但是出错了
$path="uu";//是WWW目录下的一个文件夹,我是创建了的
$d=dir($path);
while(false!==($v=$d->read()))
{
if($v=="."||$v=="..")
{
continue;
}
$file=$d->$path."\\".$v;
if(is_dir($file))
{
continue;
}
if(is_file($file))
{
echo $v."";
}
}
$d->close();
?> 


运行之后浏览器显示错误提示:Notice: Undefined property: Directory::$uu in L:\wamp\www\dynamic.php on line 20
各位前辈指点一下小生,呵呵。谢谢啦

------解决方案--------------------
$file=$d->$path."\\".$v;
改为
$file = $d->path."/".$v;
------解决方案--------------------
$file=$d->$path."\\".$v;
请把这一行改为
$file=$d->path."\\".$v;
