URL Validation

[Randomizer]

Ok, so I've been using the fsockopen function to validate URLs, but I just found it doesn't seem to work with longer paths or specific documents (ex. www.somedomain.com/path1/path2/path3/randomdoc.html), just domains (ex. www.somedomain.com). Does anybody know how to validate these kinds of documents or others like it?

Many thanks.

function http_file_exists($url, $followRedirects = true)
{
   $url_parsed = parse_url($url);
   if(!@$url_parsed['scheme']) $url_parsed = parse_url('http://'.$url);
   extract($url_parsed);
   if(!@$port) $port = 80;
   if(!@$path) $path = '/';
   if(@$query) $path .= '?'.$query;
   $out = "HEAD $path HTTP/1.0\r\n";
   $out .= "Host: $host\r\n";
   $out .= "Connection: Close\r\n\r\n";
   if(!$fp = @fsockopen($host, $port, $es, $en, 5)){
	   return false;
   }
   fwrite($fp, $out);
   while (!feof($fp)) {
	   $s = fgets($fp, 128);
	   if(($followRedirects) && (preg_match('/^Location:/i', $s) != false)){
		   fclose($fp);
	       return http_file_exists(trim(preg_replace("/Location:/i", "", $s)));
       }
       if(preg_match('/^HTTP(.*?)200/i', $s)){
	       fclose($fp);
	       return true;
       }
   }
   fclose($fp);
   return false;
}

Thanks! That worked perfectly.
