Centos 6.4 x64 - transition to MariaDB - php mysqli extension disappears somewhere

Question

PHP

In matters of unix servers, I have very little experience.
want to switch to MariaDB
Remove current packages

yum remove mysql* mysql-server mysql-devel mysql-libs

Then I install it as described here
lintut.com/install-mariadb-on-centos
everything goes well, only the php extensions associated with mysql disappear

The PHP MySql extension libraries are not installed on this server!

there really are no mysql or mysqli modules in the /usr/lib64/php/modules folder, although they were originally. I assume that the first delete command affects them as well.
re-decided to go through the steps but with the installation command

yum clean all
yum install MariaDB-server MariaDB-client MariaDB-common MariaDB-compat MariaDB-shared

but there are no modules. I tried to look for how to put them separately, but something was unsuccessful.

Answer 1

Separately:
When uninstalling, you should have been shown a list of dependencies that are also being removed.
