从php中的目录中获取所有文件名

(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.

Take a look at the Directory class (here) and readdir()

I'm confused what do you want, all files or only some files? But if you want array of folders and files, do this

$folders = array();
$files = array();
$dir = opendir("path");
for($i=0;false !== ($file = readdir($dir));$i++){
  if($file != "." and $file != ".."){
    if(is_file($file)
      $files[] = $file;
    else
      $folders[] = $file;
   }
}

And if only some folders you want, later you can delete them from array

<?php
$files=glob("somefolder/*.*");
print_r($files);
?>

I always use this amazing code to get file lists:

$THE_PATTERN=$_SERVER["DOCUMENT_ROOT"]."/foldername/*.jpg";

$TheFilesList = @glob($THE_PATTERN);
$TheFilesTotal = @count($TheFilesList);
$TheFilesTotal = $TheFilesTotal - 1;
$TheFileTemp = "";

for ($TheFilex=0; $TheFilex<=$TheFilesTotal; $TheFilex++)
  {
    $TheFileTemp = $TheFilesList[$TheFilex];
    echo $TheFileTemp . "<br>"; // here you can get full address of files (one by one)
  }
