数组后面那些长的数字+字母，是不是图片ASCii?
非常好！刚刚试了一下。另外我从上发现竟然可以用中文名作变量名！我以前以为不支持呢！
<? class S{
var $中文;
function S(){
$this->中文="xxxx";}
}
$a=new S("dd");
echo $a->中文;
$厄="hehee";
echo $厄;
?>
数组后面那些长的数字+字母，是不是图片ASCii?是图片的base64编码
sigh..改了一上午，用Tree 类样例5想做一个资源管理器没成功，路径搞的头大了，唠叨能继续修改一下吗？谢谢了

路径处理是很简单的
1、使用绝对路径
2、使用realpath()函数来处理相对路径missboy(missboy)
是吗？很同情。
不应该有此现象
