The SessionIdInterface interface

    (PHP 5 >= 5.5.1, PHP 7, PHP 8)

    简介

    SessionIdInterface is an interface which defines optional methods for creating a custom session handler. In order to pass a custom session handler to session_set_save_handler() using its OOP invocation, the class can implement this interface.

    Note that the callback methods of classes implementing this interface are designed to be called internally by PHP and are not meant to be called from user-space code.

    接口摘要

    interface SessionIdInterface {
    /* 方法 */
    public create_sid(): string
    }

    create_sid() is called when a new session id is needed.

    Such as:

    0. With PHP's default session handler, when session.use_strict_mode is turned on, if a session id provided by the client doesn't exist on the server, create_sid() is called to generate a new session id.

    1. When validateId() is provided and it returns false, create_sid() is called to generate a new session id.

    2. When session_regenerate_id() is called, create_sid() is called to generate a new session id.
