With simplexml_load_file I would like to differeniate between time out and and 404 errors

Question

I am currently using:

$page =  simplexml_load_file('http://www.example.com/page.html');

In my code I would like to retry if the page time outs, but if the page is not found ( 404 ) I would like to add it to a list of not found pages. If I could differentiate between the two types of errors I can do the rest. Any help would be appreciated.

Thanks.

Edit: For the curious you can get the status code with the following code:

if( $page == FALSE ){
  list($version,$status_code,$msg) = explode(' ',$http_response_header[0], 3);
  echo 'Status Code: '.$status_code."\n";

But for I wanted to do curl worked out better.

I think you would have to use curl for that. Curl can tell you if the request timedout or returned a 404. If neither of these happened you could just feed the results of the request to simplexml_load_string.
