This article introduces the relevant knowledge of "what is Smarty". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Introduction

Smarty is a template PHP template engine written in PHP, and it is one of the most famous PHP template engines in the industry. It separates logical code from external content, and provides an easy-to-manage and easy-to-use way to logically separate PHP code that would otherwise be mixed with HTML code. To put it simply, the purpose is to separate PHP programmers from the front-end, so that PHP programmers change the logical content of the program will not affect the front-end page design, the front-end re-modify the page will not affect the program logic, which is particularly important in multi-person cooperation projects.

2. What are the advantages of smarty?

A, speed: programs written in Smarty can achieve maximum speed improvement, which is relative to other template engine technologies.

B, compiled: programs written in Smarty are compiled into a non-template PHP file at run time, which uses a mixture of PHP and HTML to convert WEB requests directly into this file the next time the template is accessed, without template recompilation (without changes to the source program)

C, caching technology: a cache technology chosen by Smarty, which can cache the HTML file that the user finally sees into a static HTML page. When the cache attribute of Smarty is set to true, the user's WEB request will be directly converted to this static HTML file within the cachetime period set by Smarty, which is equivalent to calling a static HTML file.

D, plug-in technology: Smarty can customize plug-ins. Plug-ins are actually custom functions.

E. If/elseif/else/endif can be used in the template. It is very convenient to rearrange the template format by using the judgment statement in the template file.

3. However, you should be careful when using smarty in the following situations

A. content that needs to be updated in real time. For example, stocks show that it needs to update the data frequently, and this type of program uses smarty to slow down template processing.

B, small projects. Small projects because the project is simple and both artists and programmers are one-person projects, the use of Smarty will lose the advantage of rapid PHP development to some extent.
