This section provides a collection of miscellaneous notes on MySQL Native Driver usage. In the case where you pass a statement to mysqli_query that is longer than max_allowed_packet of the server, the returned error codes are different depending on whether you are using MySQL Native Driver (mysqlnd) or MySQL Client Library (libmysql). The behavior is as follows: mysqlnd on Linux returns an error code of 1153. The error message means got a packet bigger than max_allowed_packet bytes. mysqlnd on Windows returns an error code 2006. This error message means server has gone away. libmysql on all platforms returns an error code 2006. This error message means server has gone away. The same thing happens with mysqli_stmt_prepare.
