How can PHP be used to generate different vertical navigation menus for different sections of a website?

To generate different vertical navigation menus for different sections of a website using PHP, you can create separate PHP files for each section containing the menu items specific to that section. Then, include the appropriate menu file based on the current section being accessed using PHP include or require statements in your main template file.

// main_template.php

// Determine the current section based on the URL or any other criteria
$current_section = "products";

// Include the corresponding menu file based on the current section
if ($current_section == "products") {
    include "products_menu.php";
} elseif ($current_section == "about") {
    include "about_menu.php";
} elseif ($current_section == "contact") {
    include "contact_menu.php";
}
