//删除目录下文件方法一

 代码如下 复制代码

function clean_dir($path)        {
        if (!is_dir($path))        {
                if (is_file($path))        {
                        unlink($path);
                }
                return;
        }
        $p=opendir($path);
        while ($f=readdir($p))        {
                if ($f=="." || $f=="..") continue;
                clean_dir($path.$f);
        }
        rmdir($path);
        return;
}
//

function delFile($path,$level = 0) {

// $path $file

//删除目录下所有文件实例二

$file = "";

$lev = 0;

$dir = @opendir($path);

while($con = @readdir($dir)) {

  if($con != "." && $con != ".." && $con != "") {

   $file = $path."/".$con;

   if(is_dir($file)) {

    $lev = delFile($file,$level++);

    @rmdir($file);

   } else {

    @unlink($file);

   }

  }

}
for($i=0;$i

  delFile($path,$level);

}

@rmdir($path);

return $level;

}

delFile("./www.111cn.net");


//目录遍历函数

 代码如下 复制代码
function dirtree($path="./test") {
  echo "
";
  $d = dir($path);
  while(false !== ($v = $d->read())) {
    if($v == "."
$v == "..")
      continue;
    $file = $d->path."/".$v;
    echo "
$v";
    if(is_dir($file))
      dirtree($file);
  }
  $d->close();
  echo "
";
}

dirtree();

//php的文件系统函数比起asp教程来要强多了,删除目录所有文件只要用unlink就行了,我们只要对目录对遍历再is_file就OK了。
