最近在能php目录操作,搞了一个目录无限遍历:

使用的函数有:

isset()判断某个变量是否定义

chdir() 将当前目录改变为指定的目录。

opendir() 打开目录。

readdir()读取目录。

getcwd()。获取当前目录。

还用到了for  if  GET传值 大概就这些东东:

下面是代码:

复制代码 代码如下:
if(isset($_GET['id']))
{

    $s=$_GET['id'];
        chdir($s);
    }
echo '当前在'.getcwd(),'
';
$a=opendir('.');
while($c=readdir($a))
{
    if(is_dir($c))
    {
        $w=getcwd().'\\'.$c;
    echo $c."打开
";
    }
    else
    {
            echo $c.'
';
     }

 }

?>

大家如果有什么建议可以提出来!!谢谢!!
