With simplexml_load_file I would like to distinguish between timeout and 404 errors

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 is missing, but if the page is not found (404), I would like to add it to the list of not found pages.

If I could distinguish between the two types of errors, I could do the rest.

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 me to want to do the curl it worked better.
