mysqlnd

Bundled library, enclosed in an extension with the same name, to connect to MySQL Server 4.1+
To compile a MySQL extension : mysql or mysqli with mysqlnd, one needs to pass mysqlnd as a parameter to the configue option, like:
 --with-mysql=mysqlnd
 --with-mysqli=mysqlnd

In case of a snapshot build (--enable-snapshot-build) the MySQL extensions are built using mysqlnd instead of libmysql.
