Until 5.4 we couldn't do "mysqlnd_get_connection_stats" as there was no way to get from an arbitrary zval (PDO or mysqli object, mysql resource) to the corresponding MYSQLND*. The other reason is that one idea for mysqlnd was that it doesn't expose anything to the userland while ext/mysql is legacy and get's no additions and PDO would allow user-defined functions,while that's not really nice. > What if I choose to only compile pdo_mysql (against mysqlnd) and not > mysqli ??
