phpmyadmin: php & mysql versions differ "unpredictable behavior"

Fresh install following the debian 8 perfect server guide using ngynx and mariadb.
https://www.howtoforge.com/tutorial/perfect-server-debian-jessie-nginx-bind-dovecot-ispconfig-3.1/3/
Upon phpmyadmin login, I get this warning at the bottom:

How do I resolve this, I don't want to take any chances that it will just "be fine"

 

It is because you're using MariaDB instead of MySQL, phpmyadmin blindly thinks that 10.0.29 is MySQL version.
You can safely ignore this message.

 

Thank you for allowing me peace of mind. Will you please tell me how I may check and find out in the future if my active php versions and mariadb are fully compatible in the future? I am trying to learn how to do things proper. Thank you!

 

just do this regularly enough and you'll be good

Code:

apt-get update && apt-get upgrade
