17.7.3.6. Notes

Copyright 1997-2008 the PHP Documentation Group.

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.
