Detailed explanation of annotation and truncation functions in Smarty

Smarty is a template engine written in PHP. It separates logical code and external content, providing an easy-to-manage and use method. This article mainly introduces the annotation and truncation functions in Smarty. These two functions are not commonly used in Smarty, but they are very practical. Friends who need them can refer to them.

Comments

Copy code The code is as follows:

{* This is a single-line Smarty comment From jb51.net, invisible in the web page source code*}

{* This is a multi-line
Smarty comment
and is not sent to the browser
*}

Template comments are surrounded by asterisks, followed by delimiters, such as: {* This is a comment*}. Smarty comments will not be displayed in the output of the final template, unlike this. The former is useful for inserting internal comments in templates where no one else can see them. ;-)
