In what scenarios would it be beneficial to include navi_left.php in index.php before parsing the template with Smarty?

Including navi_left.php in index.php before parsing the template with Smarty would be beneficial when you want to load navigation elements that are required for the template to render properly. This approach ensures that the navigation elements are included in the template before any processing or rendering occurs, allowing for a seamless integration of the navigation with the rest of the page content.

<?php
include 'navi_left.php';

// Initialize Smarty
require_once('Smarty.class.php');
$smarty = new Smarty;

// Assign variables or fetch data for the template
$smarty->assign('title', 'Home Page');
$smarty->assign('content', 'Welcome to our website!');

// Display the template
$smarty->display('index.tpl');
?>
