接上面我们来看dir.php文件代码:

$dir_path=isset($_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){// 这个函数是检查并显示当前目录下的文件及文件

if(is_dir($dir_path)){

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

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

{

if($dir_list!="." && $dir_list!=".."){//如果加这里判断等一在显示文件列表时.. .这样.

echo("

".$dir_list."

}

}

}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":

return 'image/asp_php_jsp.jpg';

break;

case "aspx":

return 'image/asp_php_jsp.jpg';

break;

case "xml":

return 'image/asp_php_jsp.jpg';

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("");

echo("

");

echo("");

echo("

echo("");

}

function Tool($dir_path,$lastdir){//这里显示菜单条

echo("");

echo("");

echo("");

echo("");

echo("");

echo("");

echo("");

}

?>
