为什么在$ _SESSION时使用$ _POST? [英] why use $_POST when you have $_SESSION?
问题描述
有什么特别的原因我还应该使用$ _POST吗?
另外,我正在阅读关于会话的混合内容。 php.net说你可以通过cookie或会话ID传播会话ID:
http://www.php.net/manual/en/ref.ses...sion.idpassing
好酷。
但是,简而言之,PHP没有提到这一点。保罗只是说
嘿,使用session_start(),你就在路上:
http://hudzilla.org/phpwiki/index.ph...s_and_sessions
我测试了它,它可以工作。
有人可以解释会话ID的作用吗?
谢谢!

会话ID只是服务器上存在的记录的关键字,并且这个记录包含你写的任何会话数据它。这意味着
提供相同会话ID的不同PHP页面将连接到服务器上的
相同会话数据。这是一个网页传递给另一个网页的方式。

Is there any particular reason I should still use $_POST?
Also, I''m reading mixed things about sessions. php.net says you can
propagate session IDs either via cookies or session IDs:
http://www.php.net/manual/en/ref.ses...sion.idpassing
OK cool.
However, PHP in a nutshell makes no mention of this. Paul just says
hey, use session_start() and you''re on your way:
http://hudzilla.org/phpwiki/index.ph...s_and_sessions
I tested it out, and it works either way.
Can someone please explain what the session ID does?
Thanks!

The session ID is simply the key to a record which exists on the server, and
this record contains whatever session data you write to it. This means that
different PHP pages which provide the same session ID will connect to the
same session data on the server. This is the way that one web page passes is
state to another web page.
