How can PHP be used to dynamically change menu content based on user input?

To dynamically change menu content based on user input in PHP, you can use conditional statements to check the user input and then display different menu items accordingly. You can achieve this by using PHP variables to store the menu items and then echo out the appropriate menu items based on the user input. 

<?php
$userInput = $_GET['user_input'];

$menuItems = array(
    'home' => 'Home',
    'about' => 'About Us',
    'services' => 'Our Services',
    'contact' => 'Contact Us'
);

if($userInput == 'home') {
    echo $menuItems['home'];
} elseif($userInput == 'about') {
    echo $menuItems['about'];
} elseif($userInput == 'services') {
    echo $menuItems['services'];
} elseif($userInput == 'contact') {
    echo $menuItems['contact'];
} else {
    echo "Invalid input";
}
?>
