Desired Scenario: When a visitor arrives at a URL which normally returns a 404

  • 0

Desired Scenario:

When a visitor arrives at a URL which normally returns a 404 error, the script will first automatically discover if there are any existing pages which would provide relevant content for that page and redirect the visitor from the 404 page to that matched relevant URL (like an automatic "I’m feeling lucky" search based on the text in the otherwise 404’ing URL).

If no existing pages are deemed relevant, then the "smart 404" system would deliver the user to the 404 page.

    You can use this script: http://bobpeers.com/technical/404_redirection

    <?php 
$request=$_SERVER['REQUEST_URI'];

$arrMoved=array("/path/oldname.php"=>"/path/newname.php",
            "/old_path/oldname.php"=>"/new_path/newname.php");

if(array_key_exists($request,$arrMoved))
    {
    $newplace="http://".$_SERVER['HTTP_HOST'].$arrMoved[$request];
    header("HTTP/1.0 301 Moved Permanently");
    header("Location: $newplace");
    header("Connection: close");
    exit();
    }
else
    {
    header("HTTP/1.0 404 Not Found");
    }

?>

<!-- 
Your normal HTML code goes here since if a match is found the visitor will have been redirected. Only genuine 404 errors will see the HTML below.
 -->

<html>
  <head>
    <title>404 Error page</title>
  </head>
  <body>
    <p>Sorry but this page isn't here.</p>
  </body>
</html>
