You can use cURL:

$curl = curl_init('http://badurl.com/');
curl_setopt_array($curl, array(
   CURLOPT_NOBODY         => true, // use HEAD method, no body data
   CURLOPT_RETURNTRANSFER => true,
   CURLOPT_SSL_VERIFYPEER => false
));
curl_exec($curl);
$code = curl_getinfo($curl, CURLINFO_HTTP_CODE);

http_response_code is for setting or retrieving the response status sent back to the client invoking your PHP script, it is not for making requests out to other services located somewhere on the Internet.

You can use file_get_contents to make a request to another service, then use $http_response_header to get the headers (including the HTTP response code).

function get_response_code($url) {
    @file_get_contents($url);
    list($version, $status, $text) = explode(' ', $http_response_header[0], 3);

    return $status;
}

var_dump(get_response_code('http://badurl.com'));

This will also support all forms of URLs that file_get_contents support, including HTTPS (if compiled with SSL support).

If you want to perform a ´HEAD` request instead, to avoid having to potentially download any content (.. but which may have its own issues, where it might not return the same error code), you can either use cURL or a custom HTTP verb with file_get_contents:

file_get_contents($url,
    false, 
    stream_context_create(array(
        'http' => array(
            'method' => 'HEAD' 
        )
    )
);

Or using cURL instead:

$ch = curl_init($url);

// if you want to issue a HEAD request instead, uncomment the following
// updated from Havenard's comment - you might also want to set
// CURLOPT_SSL_VERIFYPEER to false if you don't want to verify SSL certificates.
// curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

return status;

Not like that, certainly.

Try actually getting it:

$fp = fsockopen("badURL.com",80,$errno,$errstr,1); // 1 second timeout to prevent lag
if( !$fp) echo "Failed to connect! ".$errno." ".$errstr;
else {
    fputs($fp,"HEAD / HTTP/1.0\r\nHost: badURL.com\r\n\r\n");
    $line = fgets($fp); // get first line
    fclose($fp); // not interested in the rest
    list($version,$status,$statusText) = explode(" ",$line,3);
    var_dump($status);
}
