php无限遍历目录示例
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!!
