title: is there a difference if using a slash in the query string?
body: <p>My webpage acts totally different if I use a slash before the ? in the URL. 
  (example.com/?p=1 instead of example.com?p=1 ignores the stylesheet for some reason)
  is there a difference in the variable that my script gets using the GET method? And how do I make it so that it makes no difference if I use a slash or not?
  this is some of my code</p>
  
  <pre><code>    if (isset($_GET['p'])) {
      $page = round ((int) mysql_real_escape_string($_GET["p"]));
      if ($page &gt; $tp or $page &lt; 1) {
      $page = 1;
      goto a;
      }
      else goto a;
      }
      else $page = 1;
  </code></pre>
