Re: [PHP] how do i get url: response codes?

[infoz]

Here's some code I've been using for that.  YMMV. :)

- Tim
  http://www.phptemplates.org

//
// checks $url, returns true/false and sets the response code in $response
//

function dt_checklink($url, &$response) {
  $ua = parse_url($url);
  $host = $ua[host];
  $port = ($ua[port] != 0) ? $ua[port] : 80;
  $path = ($ua[path] != "") ? $ua[path] : "/";

  $http_req = "HEAD $path HTTP/1.1\r\nHOST: $host\r\nConnection:
close\r\n\r\n";
  $http_resp = "";

  $response = "999";
  $fp = @fsockopen($host, 80);
  if ($fp) {
   socket_set_timeout($fp, 20);
   $start = time();
   fputs($fp, $http_req);
   while (!feof($fp) && ((time()-$start)<20)) {
    $http_resp .= fgets($fp, 256);
   }
   fclose($fp);
   if (ereg("HTTP/[0-9]\.[0-9] ([0-9][0-9][0-9]) ", $http_resp, $regs)) {
    $rcode = $regs[1];
    $response = $rcode;
    if ($rcode == 200) return true; // OK
    if ($rcode == 301) return true; // document moved
    if ($rcode == 302) return true; // document moved
    return false;
   }
   return false;
  }
  return false;
 }
