我最近从PHP 7.2切换到7.3，并且启用它后，收到此消息，但不确定是错误还是出于参考目的：
sudo a2enmod php7.3
Considering dependency mpm_prefork for php7.3:
Considering conflict mpm_event for mpm_prefork:
Considering conflict mpm_worker for mpm_prefork:
Enabling module mpm_prefork.
Considering conflict php5 for php7.3:
Enabling module php7.3.
To activate the new configuration, you need to run:
service apache2 restart
我需要做任何事情吗？它在重新启动apache之后运行。
