I am trying to get a list with folders and sub folders i have the following that allows me to get the folders and sub folders but i needed it to be sorted out like the e.g below i have been trying but i dont know how i would get around.

Root/
Root/Images
Root/Images/UserImages

Root/Text/

PHP 代码:

    function ListFolder($path)
{

    $dir_handle = @opendir($path) or die("Unable to open $path");

    //Leave only the lastest folder name
    $dirname = end(explode("/", $path));

    //display the target folder.
    echo ("$dirname/");
    while (false !== ($file = readdir($dir_handle)))
    {
        if($file!="." && $file!="..")
        {
            if (is_dir($path."/".$file))
            {
                //Display a list of sub folders.
                ListFolder($path."/".$file);
                echo "<br>";
            }
        }
    }


    //closing the directory
    closedir($dir_handle);
}

    ListFolder("../");

谢谢

推荐答案

将目录名收集到一个数组中，而不是直接echo.在数组上使用 sort 和 foreach 循环来打印列表.

Collect the directory names in an array instead of echoing them directly. Use sort on the array and a foreach-loop to print the list.

所以代替 echo ("$dirname/"); 你会使用 $dirnames[] = $dirname; (使 $dirnames 全局并在你之前初始化它第一次调用ListFolder").然后在递归运行ListFolder"之后，您将执行 sort($dirnames); 然后像这样的输出:

So instead of echo ("$dirname/"); you would use $dirnames[] = $dirname; (make $dirnames global and initialize it before your first call of "ListFolder"). Then after the recursive run of "ListFolder", you'd execute sort($dirnames); and then something like this for the output:

foreach ($dirnames as $dirname)
{
  echo $dirname . '<br />';
}
