РНР скрипт работает плавник е. Для загрузки требуется около 0,03. Но когда скрипт достигает класса CalendarExpiryItemList. Это занимает около 30 секунд, и мой сервер отключается.

В каждой таблице должно быть от 12 до 15 полей в среднем и от 10 до 100 записей.

Я нахожусь на хостинге с хостинговой компанией, у них есть балансиры нагрузки. Поэтому, если мои сценарии занимают более 30 секунд, балансировщик нагрузки сбрасывает мое соединение и возвращает сообщение об ошибке «Сервер не отправил никаких данных»

Answer 1

Как говорят другие, попробуйте просмотреть свой код.

... не имея возможности отлаживать код, возможно, один или несколько методов в классе CalendarExpiryItemList тоже не работают; по запросу или связанному запросу или возвращению бесконечного цикла. Вы должны тестировать и отлаживать каждый метод индивидуально на своем тестовом сервере, чтобы узнать, какие результаты вы получаете. Для быстрого и грязного теста просто зарегистрируйте вывод каждого метода в файл. Также проверьте $ _SESSION ['user_id'] значение и используйте ". (Int) $ _SESSION ['user_id'], а затем перед отправкой его db в случае, если он пуст, потому что он не экранирован.
