We can see that the program part of smarty is actually a set of codes that conform to the PHP language specification. Let’s explain them in turn:
1. /**/Statement: The part contained in
is the program header comment. The main content should be a brief introduction to the function of the program, copyright, author and writing time. This is not necessary in smarty

2. include_once statement:
It will include the smarty file installed on the website into the current file. Note that the included path must be written correctly.
3. $smarty = new Smarty():
This sentence creates a new Smarty object $smarty, which is a simple instantiation of an object.
4. $smarty->templates(""):
This sentence specifies the path of the $smarty object when using the tpl template. It is a directory. Without this sentence, Smarty's default template path is templates in the current directory

This sentence specifies the directory where the $smarty object is compiled. In the template design chapter, we already know that Smarty is a compiled template language, and this directory is the directory where it compiles
templates. Note here that if the site is located on a *nix server, please ensure that this directory is defined in teamsplates_c It has writable and readable permissions. By default, its compilation directory
is templates_c in the current directory. For the same reason, we write it out explicitly.
6. $smarty->left_delimiter and $smarty->right_delimiter:
Indicates the left and right delimiters when looking for template variables. By default, it is "{" and "}", but in practice, because we need to use
