I have my own dedicated server running CentOs Linux 7. please do explain the solution in steps as I am not a professional. Thanks!

You need to update the PHP mysql extension to match the updated mysql. — Barmar, Sep 05 '17 at 18:36
yum -y remove mysql56w-mysql && yum -y install php56w-mysqlnd — kodmanyagha, Jan 08 '19 at 13:43

Your PHP was compiled with different MySQL version and now it is linking a mysql library of different version. You have to upgrade PHP to a version compiled with MySQL or revert back mysql client libraries to lower.

One option is to pull the mysqli.so file from a server with PHP compiled with MySQL and just add it in /usr/lib/php5/ directory. This worked for me. If this does not, try solutions in similar question here - Headers and client library minor version mismatch
