2. is a combined project

The problem I encountered here is the position of the front desk. It was written at the beginning,

Because you want to change to 5 format, see the foreground needs to use {$Request. Session.name} or {$Think. session.name} format, but I have used the PHP tag to use this will be the error, because he is the default parsing into <?php Echo ....? > in the format. So I changed into this.

In the final analysis, the problem is the TP5 version of the session information how to output in the foreground, and in the output before the use of PHP preprocessing (such as some simple judgments of judgment).

And then the digression is through the editor of this article, I find myself in verbal expression or in this way too weak to grasp, I need a certain amount of time to improve myself, laziness is a very important factor, I think I can overcome these, because I can not endure such a weak self, I have to be a good enough person. A little progress.
