title: Open directory in server side and open files inside it
body: <p>I have a directory inside my server full of PDF files and I would like to open the file and be able to click on the name of the PDF and watch its content.  Now I only get the names of the files in a list but thats all.  I would like to press in the name and open the PDF.  </p>
  
  <pre><code>&lt;?php 
  $sub = ($_GET['dir']); 
  $path = 'pedidos/'; 
  $path = $path . "$sub"; 
  $dh = opendir($path); 
  $i=1; 
  while (($file = readdir($dh)) !==   false) {
    if($file != "." &amp;&amp; $file != "..") {
        if (substr($file, -4, -3) =="."){
            echo "$i. $file &lt;br /&gt;";
        }else{                  
            echo "$i. &lt;a href='?dir=$sub/$file'&gt;$file&lt;/a&gt;&lt;br /&gt;";
        }
        $i++;
     } } 
  closedir($dh); ?&gt;
