PHP: scandir() is too slow

I have a directory with tens of thousands of files in it and I want to display a list of these files on a page. I tried doing it with scandir and it takes forever. What would be an efficient method of achieving this?

I recommend using DirectoryIterator or RecursiveDirectoryIterator.

I haven't benchmarked them, but your other options are

glob() - http://php.net/manual/en/function.glob.php

opendir() - http://www.php.net/manual/en/function.opendir.php

$directory=opendir($_SERVER['DOCUMENT_ROOT'].'/directory/');
  while ($file = readdir($directory)) {
    if($file!="." && $file!=".."){
      echo $file."<br>";
    }
  }
closedir($directory);
