Smarty is a template engine written in PHP and is one of the most famous PHP template engines in the industry.

It separates logical code from external content and provides an easy way to manage and use it.

2. It is used to logically separate PHP code from HTML code.

Simply speaking, the purpose is to separate PHP programmers from front-end personnel, so that programmers change the logical content of the program will not affect the front-end personnel page design, front-end personnel to modify the page will not affect the program logic, which is particularly important in multi-person cooperation projects.

advantages

(1) Speed: Programs written with Smarty achieve maximum speed improvements relative to other template engine technologies.

(2) Compile type: The program written by Smarty should be compiled into a PHP file with non-template technology at runtime. This file adopts a mixed way of PHP and HTML. When accessing the template next time, the WEB request will be directly converted into this file without recompiling the template (in the case of no change in the source program).

(3) Cache technology: Smarty selects a cache technology, 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 is directly converted to this static HTML file during the cachetime period set by Smarty, which is equivalent to calling a static HTML file.

(4) Plug-in technology: Smarty can customize plug-ins. Plugins are actually custom functions.

(5) You can use if/elseif/else/endif in templates. The use of judgment statements in template files can be very convenient for reformatting templates.

Not suitable for Smarty

Content that needs to be updated in real time. For example, a stock display, which needs to update data frequently, uses smarty to slow down template processing for this type of program.

Small projects. Small projects because the project is simple and the artist and programmer are in one project, using Smarty will lose the advantages of PHP development to some extent.

(PS: But for the sake of project specification, please try using template engines.) In fact, used to, the development speed will be faster, the above is not used to template engine developers encountered problems)

Thank you for reading, the above is the "PHP Smarty introduction" content, after the study of this article, I believe we have a deeper understanding of the introduction of PHP Smarty this problem, the specific use of the situation also needs to be verified by practice.
