1. what is smarty?
Smarty is a PHP template engine written by the application PHP. It provides the logic and external content respectively. In short, the goal is to use PHP programmers to share the same job score with the US.
The logic content of the application programmer's transformation program does not affect the page design of the artist, and the art's re-correction page does not affect the program logic.
Is particularly important.

II. Advantages of smarty:

When asked about the template, the WEB request is directly converted to this file, instead of re-compiling the template (if the source program is not corrected)

3. cache skills: smarty uses a caching technique that caches the HTML files that users can ultimately see into a static HTML page. when the cache attribute of smarty is set
If it is set to true, the user's WEB request is directly converted to this static HTML file during the cachetime period set by smarty, which is equivalent to calling a static HTML file.
