SessionHandler::close

Function name: SessionHandler::close()

Applicable version: PHP 5 >= 5.4.0, PHP 7, PHP 8

Function Description: The SessionHandler::close() method is called at the end of the session and is used to close the session processor.

usage:

 bool SessionHandler::close(void): bool

parameter:

• No parameters

Return value:

• Returns a Boolean value indicating whether the session processor successfully closes the session.

Example:

 <?php class MySessionHandler implements SessionHandlerInterface { public function open($savePath, $sessionName) { // 实现打开会话处理器的逻辑return true; } public function close() { // 实现关闭会话处理器的逻辑return true; } public function read($sessionId) { // 实现读取会话数据的逻辑return ''; } public function write($sessionId, $data) { // 实现写入会话数据的逻辑return true; } public function destroy($sessionId) { // 实现销毁会话数据的逻辑return true; } public function gc($maxLifetime) { // 实现垃圾回收的逻辑return true; } } // 设置自定义的会话处理器$handler = new MySessionHandler(); session_set_save_handler($handler); // 开启会话session_start(); // 会话逻辑... // 关闭会话session_write_close(); ?>

In the above example, we created a custom session processor, MySessionHandler , which implements all methods of the SessionHandlerInterface interface, including the close() method. After setting up a custom session processor using the session_set_save_handler() function, we can close the session by calling session_write_close() method. At this time, close() method of MySessionHandler class will be automatically called to close the session processor.
