RTM ;-)

If data size of a variable exceeds max. allowed packet size (max_allowed_packet), you have to specify b in types and use mysqli_stmt_send_long_data() to send the data in packets.

So I have never done this myself but i would assume it needs to look something like this based on your code and the example on the functions doc page:

    $filepath = ini_get('upload_tmp_dir')."/".basename($_FILES['file'.$i]['tmp_name']);
    $filepath = addslashes($filepath);
    $handle = fopen($filepath, "rb");
    $content = null;

    $stmt = $mysqli->prepare("INSERT INTO attachment (filename,filecontent,mkey) VALUES (?,?,?)");
    $stmt->bind_param("sbi",$_FILES['file'.$i]['name'], $content, $mkey);

    while (!feof($handle)) {
        // $maxPacketSize would be the size of your max packet setting for mysql,
        // or something safely assumed to be below it
        $stmt->send_long_data(1, fread($handle, $maxPacketSize));
    }
    fclose($handle);
    $stmt->execute();
