Гостевая книга на PHP

Этот PHP пакет может использоваться для организации и управления гостевой книгой или простым блогом используя базу данных MySQL. Он может создать необходимую таблицу в базе данных MySQL для хранения записей о гостевой книге, которая может также работать как простой блог.

Пакет выполняет несколько действий по управлению гостевыми книгами, такие как: добавление новых записей, отправка сообщений по электронной почте для проверки пользователей добавляющих записи, поиск и отображение записей в гостевой книге, подтверждение или удаление гостевых книг.

Лицензия - свободно для образовательных целей.
