mysqlnd is a new core library shipped with PHP.
It is a PHP-specific replacement for libmysqlclient. mysqlnd will
be used to build the mysql, mysqli and PDO_MySQL extensions if libmysqlclient isn’t found on
the system. It may also be used instead of libmysqlclient even when
libmysqlclient is present. mysqlnd is recommended for all PHP
installations for performance reasons.
