Is there anyway using PHP to send a command to a server to get the get eather a 404 or 200 reply?

Here's a function I put together to do just that. It takes a full URL as an argument and returns either boolean true, boolean false, or a string error message. Since it might return a string error you need to check the type returned when using it, such as: <? if($http_file_exists("http://someurl.tld/page.html") === true) { //do stuff } ?> Note the three equals signs that checks for type as well as value. Anyway, here is the function: <? function http_file_exists ($url) { if (!preg_match("/^http:\/\/([^\/]+)\/.*$/i",$url,$matches)) {

    return "Error - incorrect format";

} else {

    $host = $matches[1];
    $fp = fsockopen ($host, 80, $errno, $errstr, 30);

    if (!$fp) return "Error - couldn't connect to host";
      else {
        fputs ($fp, "HEAD $url HTTP/1.0\r\n\r\n");
        $response = fgets ($fp,128);
        fclose ($fp);
        return (eregi("^.+200 OK.+$",$response) ? true : false);
      }

} } ?>
