PHP遍历文件夹下的文件和获取到input name的值,

$dir = dirname(__FILE__); //要遍历的目录名字 ->当前文件所在的文件夹
//$dir='D:\PHP\wamp\www\admin\hosts\admin'; 
//PHP遍历文件夹下所有文件 
$handle=opendir($dir."."); 
$arr = array();
while($file=readdir($handle)){ 
  if(is_file($file)){
    if ($file != "."&& $file != "..") {
      $file = mb_substr($file,0,strripos($file,'.'));
      $files = explode(' ',$file); //把$file转换成数组
      $arr[]=$files['0'];//转换成一维数组
    }
  } 

//print_r($arr);
closedir($handle); 
//PHP获取input->name的值
foreach ($_POST AS $key=>$value){
  if(!in_array($key,$arr)){ //判断name值在不在$arr里面
    echo "$key:不存在";
}

}
?>
