This question is for Centos 6.4:

Will installing the PHP module “php-mysql” over-write anything critical to Percona Server’s functioning?

Should I install the module?

Thanks!

This is non-relevant with MySQL or Percona servers, if you want to use MySQL or Percona Server with PHP then you probably need php-mysql api, I’d suggest to use PDO. These are completely different and would not interfare with your server. Ans mind you, Percoan server is 100% MySQL.
