List Dropbox folder content in a website - php snippet

This is a quick and dirty PHP script, to embed the contents of a publicly accessible Dropbox folder as a list of files within your website. Use at your own risk!

To use this script,call it with the following command:    
  $dropboxURL = 'SpecifyApubliclyAccessibleDropboxUrl';
  print get_data($dropboxURL);    
function get_data($url) {  
  // Grab the dropbox page 
  $ch = curl_init();
  $timeout = 10;
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);   
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
  $result = curl_exec($ch);
  // Parse the links out of the HTML
  $string = "";       
  $uniqelinks = array(); 
  // For some reason the are duplicate links so lets make then unique
  foreach($links as $link) $uniqelinks[$link] = $link; 
  // Loop through the links and build and HTML list
  foreach($uniqelinks as $link){   
      $char = strlen($link);
  	  $pref = $link[$char-4].$link[$char-3].$link[$char-2].$link[$char-1];
  	  $class = str_replace('.','',$pref);   
  	  $title = explode('/', $link);  
  	  $title[6] = str_replace('%20', '&nbsp;', $title[6] ); 
  	  if($pref=='.pdf' || $pref=='.jpg' || $pref=='.gif' || $pref=='.zip'){
  		  $string .= "<div class=\"file\"><a href=\"$link\" class=\"icon $class\">".$title[6]."</a></div>"; 
  return $string;
