Listing Files or Directories with PHP

How to list files with PHP using the DirectoryIterator class.

<?php
 // the folder to list
 $images = 'images/';
 // directory iterator
 foreach (new DirectoryIterator($images) as $fileInfo) {
   if($fileInfo->isDot()) continue;          
   // echo the image out and the filename
   ?>
   <img src="<?php echo $images . $fileInfo->getFilename();?>" />
   <br />
   <?php echo $fileInfo->getFilename(); ?>
 <?php          
 }
 ?>

Put this code in a .php file on your web server as a starting point for listing files. It will list any files and folders that aren't "Dot" files -- which are "." and "..", which relate to the current directory and the parent directory, respectively.
