other templates referenced in the
 template are {include file= "header.html"} 
 for example, index.php 
 template is $smarty- > display ("index.html"), 
 then the header template file {include file= "header.html"}, 
so if, in this header.html, there are some parameters that need to be controlled by his back-end console, that is, header.php, in this case, how can index.html refer to header.php, and let header.php output the template $smarty- > display ("header.html")?
how to deal with this situation? Thank you very much for your advice.
