MySQL_ND and MySQL PHP extensions are the different sets of drivers. They are 
provided by the different teams of developers (MySQL and PHP, respectively). 
The most important is the fact that they are mutually exclusive - you can not 
select them both simultaneously or mix them in any way. Otherwise, the php code 
will throw errors about the connection to the MySQL database.

Since PHP 5.4, mysqlnd is used as the default MySQL driver for all PHP MySQL 
extensions. But for PHP 5.3 and older PHP versions libmysqlclient is used as a 
connector from PHP to MySQL.

For PHP Selector we need to support both methods, that is why we added nd_* 
prefix for PHP MySQL extensions compatible with mysqlnd.

So, as a result:
- libmysqlclient works with  mysql, mysqli, pdo_mysql extensions (PHP 4.4 - PHP 5.3);
- mysqlnd works with nd_mysql, nd_mysqli, nd_pdo_mysql extensions (PHP 5.4 - PHP 7.1+).

So you have to choose only one of the following sets:

mysqlnd && nd_mysql && nd_mysqli && nd_pdo_mysql

###################### OR ########################

mysql && mysqli && pdo_mysql
