Thanks for the invitation.
It’s just a syntax for a template engine implemented by yourself.
~php~~ is equivalent to <?php
~/php~~ is equivalent to ?>

As for ~$tit~~, it is equivalent to the short markup syntax

I haven’t seen it before, but it shouldn’t have any special meaning. It’s a template tag customized by a niche engine. It should be equivalent to

<code><?php echo date('Y')?>
<?php echo $tit?>
<?php echo $jscode?></code>

It has no research value, you can just write it like this.

Thank you for the invitation. This should be a custom short tag

The front should be a copyright statement, and the back is a grammatical issue.
