Сообщение: mysqli :: real_connect (): ( HY000 / 2002): соединение отклонено

Как мы можем это исправить?

Answer 1

для других БД необходимо установить с тем же именем. Пожалуйста, исправьте с помощью следующего кода

$db['otherdb']['username'] = '***********';
$db['otherdb']['password'] = '***********';
$db['otherdb']['database'] = '***********';
