List only some extention (File Listing)

Good day to you all,
I'm working on a pice of code which list all files in a directory and return the list and its content right under the name of the file.

<?php
$thelist = "";
 if ($handle = opendir('.')) {
   while (false !== ($file = readdir($handle)))
      {
          if ($file != "." && $file != "..")
	  {
          	$thelist .= '<a href="'.$file.'">'.$file.'</a><br/>';
            $contents = file($file);
            $string = implode($contents);
            $thelist .= '<p>'.$string.'</p>';
            
          }
       }
  closedir($handle);
  }
?>
<P>List of files:</p>
<P><?=$thelist?></p>

PHP:

I'm looking for a way of choose only 3 or 4 extension only.

How would I dow so ?

Thanks !

 

hi

where it says

          if ($file != "." && $file != "..")

Code (markup):

replace with

          if (eregi("txt$",$file) || eregi("jpg$",$file) || eregi("gif$",$file))

Code (markup):

replace extension how you need, add more if needed.

enjoy
