SessionHandler::destroy

Function name: SessionHandler::destroy()

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

Usage: The SessionHandler::destroy() function is used to destroy the specified session data. It is an abstract method that needs to be implemented in a custom session processor class.

grammar:

 public SessionHandler::destroy(string $session_id): bool

parameter:

• $session_id: The session ID to be destroyed.

Return value:

• Returns true on success, and false on failure.

Example: The following example demonstrates how to implement the SessionHandler::destroy() method in a custom session processor class:

 class MySessionHandler extends SessionHandler { public function destroy(string $session_id): bool { // 在此处编写自定义的会话销毁逻辑// 例如，从数据库或文件系统中删除会话数据$result = // 执行销毁操作的代码return $result; // 返回操作结果} } // 使用自定义的会话处理器类$handler = new MySessionHandler(); session_set_save_handler($handler, true); // 销毁指定的会话数据$session_id = 'abcdef1234567890'; // 要销毁的会话ID $result = $handler->destroy($session_id); if ($result) { echo '会话数据已成功销毁。'; } else { echo '会话数据销毁失败。'; }

In the above example, we create a custom session processor class called MySessionHandler , inherited from SessionHandler . In this class, we override destroy() method and implement custom session destroy logic in it. Then, we set the custom session processor class to the current session processor through session_set_save_handler() function. Finally, we call destroy() method to destroy the specified session data and output the corresponding message based on the returned result.
