@get_headers

My code below works when it wants?
It seems to me something is firing too quickly...

If someone has a minute to look over it, that would be great.

include dirname(__FILE__) . "/db.php";
 
$search_id = $_GET['id'];
 
$q = mysql_query("SELECT download_url FROM searches WHERE search_id = '$search_id'") or die(mysql_error());
$row = mysql_fetch_row($q);
$download_url =  $row[0];
 
$file_headers = @get_headers(urldecode($download_url));
            if ($file_headers[0] == 'HTTP/1.1 404 Not Found' || $file_headers[0] == 'HTTP/1.1 403 Forbidden' || $file_headers[0] == 'HTTP/1.1 301 Moved Permanently') {
            echo 'Thanks and well spotted, our system has deleted this file link from the database.';
            mysql_query("DELETE FROM searches WHERE search_id = '$search_id'") or die(mysql_error());
            } else {
            echo 'Hmmm...it seems as though this file link is a valid one and should play?<br /><br />Would you like to tell us more about the problem you are experiencing?<br /><br /> <a href="contactus.php">Contact Us</a>';
  }

you should also check if get_headers() returned false
