Я создаю базу данных, которая будет взаимодействовать с таблицей SQL.
Чего я достиг на данный момент:
- Добавить строки в таблицу.
- Удалить строки из таблицы.
- Поиск строк из таблицы.
- Разбиение результатов на страницы.
Что мне нужно сделать:
- Запрос на вход в системукогда гость пытается получить доступ к странице.
На самом деле я успешно установил для него скрипт входа в систему, но, похоже, он не работает должным образом, вот ошибка:
Неустранимая ошибка: допустимый объем памяти 25165824 байта исчерпан (попытка выделить 77824 байта) в /home/vol3/byethost12.com/b12_3598660/htdocs/coordbase/database.php в строке 238
Теперь, когда у меня нет разрешения на выделение памяти моему хосту, мне нужно было бы обойти это.Я уже пытался разделить файл на несколько страниц, но кажется, что он все еще пытался выделить одинаковое количество байтов.
Вот файл:
