如何调用会话变量？ [英] How to call the session variable?

问题描述

正如您所建议的那样，我没有使用session_register（）。在一个

文件中，我执行了这样的行：

$ _session [''ex''] = 2.0;


然后，在另一个文件中，我执行了以下行：

$ ex = 3.0。


而且我注意到之前的任务被看到了/>
无处不在（在其他页面上）。所以，据我所知，在$ _session [''ex''] = 2.0的
使用后，$ ex变量成为会话

变量。而且，$ ex和

$ _session [''ex'']变量是同一个变量！换句话说，我只需要第一次拨打$ _session [''ex'']。我做了一次

后我只能使用$ ex（而不是$ _session [''ex'']）。这是真的吗？

Hi,

As you have recommended I did not use the session_register(). In one
file I have executed such line:
$_session[''ex''] = 2.0;

Then, in another file, I have executed the following line:
$ex = 3.0.

And than I have noticed that the previous assignment is seen
everywhere (on other pages). So, as far as I understood, after the
usage of $_session[''ex''] = 2.0, the $ex variable becomes a session
variable. Moreover, $ex and
$_session[''ex''] variables are the same variable! In other words, I
have to call $_session[''ex''] just the first time. After I did it once
I can use just $ex (instead of $_session[''ex'']). Is that true?

推荐答案

_session [''ex''] = 2.0;


然后，在另一个文件中，我执行了以下行：

_session[''ex''] = 2.0;

Then, in another file, I have executed the following line:

ex = 3.0。


而且我注意到了之前的行在任何地方看到分配

（在其他页面上）。所以，据我所知，在

使用

ex = 3.0.

And than I have noticed that the previous assignment is seen
everywhere (on other pages). So, as far as I understood, after the
usage of

_session [''ex''] = 2.0后，

_session[''ex''] = 2.0, the
