Список параметров
Возвращаемые значенияReturns an array of associative or numeric arrays holding result rows. Только для MySQL Native DriverДоступно только с расширением mysqlnd. As mysqli_fetch_all() returns all the rows as an array in a single step, it may consume more memory than some similar functions such as mysqli_fetch_array(), which only returns one row at a time from the result set. Further, if you need to iterate over the result set, you will need a looping construct that will further impact performance. For these reasons mysqli_fetch_all() should only be used in those situations where the fetched result set will be sent to another layer for processing. Смотрите также
