How can PHP sessions impact the navigation flow of a website?

PHP sessions can impact the navigation flow of a website by allowing you to store user-specific information across multiple pages. This can be useful for keeping track of a user's login status, shopping cart items, or other personalized data. To ensure a smooth navigation flow, make sure to start the session at the beginning of each page where you need to access session variables and destroy the session when the user logs out or their session expires. 

// Start the session at the beginning of each page
session_start();

// Set session variables
$_SESSION['user_id'] = 123;
$_SESSION['username'] = 'john_doe';

// Access session variables on other pages
$user_id = $_SESSION['user_id'];
$username = $_SESSION['username'];

// Destroy the session when the user logs out
session_destroy();
