La interfaz SessionUpdateTimestampHandlerInterface

(PHP 7, PHP 8)

Introducción

SessionUpdateTimestampHandlerInterface es una interfaz que define métodos opcionales para la creación de un gestor de sesión personalizado. Con el fin de pasar un gestor de sesión personalizado a la función session_set_save_handler() utilizando su invocación OOP, la clase puede implementar esta interfaz.

Se debe tener en cuenta que estos métodos están destinados a ser llamados de manera interna por PHP, y no desde el espacio de usuario.

Sinopsis de la Clase

interface SessionUpdateTimestampHandlerInterface {

/* Métodos */

public function updateTimestamp(string $id, string $data): bool

public function validateId(string $id): bool

}

I found that the updateTimestamp has special function.

Seems this was specifically meant for updating timestamp for Cookie based session.

When we use Cookie as a mode of storage of session data we need to maintain the timestamp inside the cookie data.

Generally, when we use other modes we have timestamp details for when it was last accessed. I. case of Cookie this details is with browser as the modified data is set at that moment but not inside the cookie.

So, if we need the last accessed timestamp we can add a kay for the timestamp.

The hack is we need to use session option ['serialize_handler' => 'php_serialize'] so that unserialize add required timestamp key and re serialize it.

I think the 'php_serialize' is the only option which helps to decode the sessionData inside the Session Handler class.
