从php中的目录中获取所有文件名

Question

(Well what I gone through a lot of posts here on stackoverflow and other sites. I need a simple task, )

I want to provide my user facility to click on upload file from his account, then select a directory and get the list of all the files names inside that directory.

According to the posts here what I got is I have to pre-define the directory name, which I want to avoid.

Is there a simple way to click a directory and get all the files names in an array in PHP? many thanks in advance!

  $dir = isset($_POST['uploadFile']) ? _SERVER['DOCUMENT_ROOT'].'/'.$_POST['uploadFile'] : null;
  if ($_POST['uploadFile'] == true) 
    {
     foreach (glob($dir."/*.mp3") as $filename) {
     echo $filename;
    }
  }

I will go ahead and post a sample of code I am currently using, with a few changes, although I would normally tell you to look it up on google and try it first.

if ($handle = opendir($dir)) {
    while (false !== ($file = readdir($handle))) {
        echo $file;
    }
    closedir($handle);
}

This will display the entire contents of a directory... including: ".", "..", any sub-directories, and any hidden files. I am sure you can figure out a way to hide those if it is not desirable.
