[SOLVED] What the different between MySQL Native Driver and MySQL Client Library

I want to know the different between MySQL Native Driver and MySQL Client Library and when to use both of them

There is no big difference in the PHP language level.

libmysqlclient distributed by MySQL, mysqlnd distributed by PHP.
libmysqlclient is part of MySQL, you need install MySQL library.
Their license are different.
mysqlnd supports a lot of plugins (mysqlnd_ms & mysqlnd_qc & ...).
Because mysqlnd is part of PHP, its memory could be limited by PHP configuration.
mysqlnd is the default after 5.4
