我想知道是否可以在会话到期时将会话数据保存到数据库或文件中。例如，当我的会话中有一个对象时，会话到期时会调用析构函数吗？
基本上，问题是PHP如何在会话过期时处理会话。
谢谢你的帮助！
看起来您可以使用session_set_save_handler函数定义一个回调，该回调在会话被破坏时被调用。
顺便说一句，我想问一下，在会话超时时保存数据，而不仅仅是在会话期间保存数据，这是否是一个好的设计。
要更改会话的最长生存期，请尝试以下操作：
ini_set("session.gc_maxlifetime", "18000");
这将使寿命设置为5小时。您必须在每个要更改其默认生存期的脚本中使用此选项。
要获取会话的生存期：
echo ini_get("session.gc_maxlifetime");
