How can PHP developers efficiently handle the display of submenus based on the currently selected menu item?

To efficiently handle the display of submenus based on the currently selected menu item, PHP developers can use conditional statements to determine which submenu to display. By checking the current page or menu item, developers can dynamically show or hide the appropriate submenu. 

<?php
$current_page = "home"; // Assuming the current page is "home"

// Display submenu based on the current page
if ($current_page == "home") {
    // Display home submenu
    echo "Home Submenu";
} elseif ($current_page == "about") {
    // Display about submenu
    echo "About Submenu";
} elseif ($current_page == "services") {
    // Display services submenu
    echo "Services Submenu";
} else {
    // Display default submenu
    echo "Default Submenu";
}
?>
