Continuing from the above, let’s look at the dir.php file code:

$dir_path=isset($_GET['url'])?$_GET['url']:'..';

//$totallen = strlen($dir_path);

//$sublen = strlen(substr($dir_path,strrpos($dir_path,"/")));

$lastdir = substr($dir_path,0,strlen($dir_path)-strlen(substr($dir_path,strrpos($dir_path,"/"))));

Tool($dir_path,$lastdir);

CheckDir($dir_path);

//echo "
";

//echo substr($dir_path,0,(strlen($dir_path)-strrpos($dir_path,"/")+1));

function CheckDir($dir_path){// This function checks and displays the files and files in the current directory

if(is_dir($dir_path)){

If($dir_file=opendir($dir_path)){

While(($dir_list=readdir($dir_file))!==false)

{

If($dir_list!="." && $dir_list!=".."){//If you add this to judge and wait until the file list is displayed... like this.

       echo("

".$dir_list."

\n");

      }

     }

   }else{

    echo($dir_path."
");

   }

  }else{

   echo($dir_path."
");

  }

  Folderexp($dir_path);

}

function Getfiletype($dir){//根据扩展名显示相应的图片

 global $_GET;

 if(@$_GET['url'] !='' and is_dir(@$_GET['url'])){

  $dir = $_GET['url'].'\\'.$dir;

 }

 //print_r( $dir);

 if($dir == '' || is_null($dir) || empty($dir)){return false;}

  if(is_dir($dir)){

   return 'fold.jpg';

  }else{

   return (Getextends($dir));

  }

}

 

 

function Getextends($dir){

 if($dir =="" || is_null($dir)){return "unkown.jpg";}

  $Extends_name = substr($dir,strrpos($dir,".")+1); 

  $Extends_img = array('jpg','jpeg','gif','png','bmp','psd'); 

 if(in_array($Extends_name,$Extends_img)){return $dir;}

   switch($Extends_name){

    case "php":

     return 'image/asp_php_jsp.jpg';

     break;

    case "asp":

     return 'image/asp_php_jsp.jpg';

     break;

    case "jsp":

    case "xml":

     return 'image/asp_php_jsp.jpg';

     break;

    case "htm":

     return 'image/html_js.jpg';

     break;

    case "html":

     return 'image/html_js.jpg';

     break;

    case "shtml":

     return 'image/html_js.jpg';

     break;

    case "js":

     return 'image/html_js.jpg';

     break; 

    case "txt":

     return 'image/txt.jpg';

     break;

    case "doc":

     return 'image/word.jpg';

     break;

    default:

     return 'image/fold.jpg';

     

   }

}

function Folderexp($dir_path){//新建文件夹

  echo("

  echo("

  echo("");
