Introduction to annotation and truncation functions in Smarty, introduction to smarty truncation function

Annotation
Copy code The code is as follows:
{* This is a single-line Smarty comment from jb51.net, which cannot be seen in the source code of the web page*}

{* This is a multi-line
Smarty Notes
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. ;-)
