If you die you won't reach the return. @PhpMyCoder

   if (!isset($servers[$ext])){
       $output="no match data!";
    }
    return(json_encode($output));

I think you're looking for something like this:

The PHP file:

if (!isset($servers[$ext])){
    $output = 'no match data!';
}
// for good measure, tell the client json is coming back.
header('Content-type: application/json');

echo(json_encode($output));

return;

The JavaScript remains the same.

Your ajax request is expecting json. In jQuery 1.4 malform json will be rejected.

If you want to return html, set 

dataType:"html",

Or set your die statement to return json.

why using the "die" function while you just want to echo something as an answer from the server? Remember that when you are using an ajax request, there is not much this request will be able to grab as a response. You'll be able to catch any HTTP response code, its associated text + any text answer.

Simply echo something, json_encode them if you want to have more flexibility in handling multiple values in javascript and that'll do!
