PHP:

                                  $type = filter_var($text[1], FILTER_SANITIZE_NUMBER_INT);
                                  $level = filter_var($text[3], FILTER_SANITIZE_NUMBER_INT);
                                  $enchantment = Enchantment::getEnchantment($type);
                                  $enchInstance = new EnchantmentInstance($enchantment, $level);
                                  $item = $player->getInventory()->getItemInHand();
                                  $item -> addEnchantment($enchInstance);
