Notatki

Informacja:

MySQLnd zawsze przyjmuje domyślne kodowanie znaków serwera. To kodowanie jest przesyłane podczas połączenia hand-shake/authentication, którego używa mysqlnd.

Libmysql używa domyślnego kodowania znaków ustawionego w pliku my.cnf lub przez jawne wywołanie funkcji mysqli_options() przed wywołaniem mysqli_real_connect(), ale po wywołaniu mysqli_init().
