How does PHP handle session storage and management?

PHP handles session storage and management by storing session data on the server and assigning a unique session ID to each user. This session ID is then stored in a cookie on the user's browser. PHP provides built-in functions to start, access, and destroy sessions, making it easy to manage user data across multiple pages. 

// Start a session
session_start();

// Set session data
$_SESSION['username'] = 'JohnDoe';

// Access session data
echo 'Welcome back, ' . $_SESSION['username'];

// Destroy session
session_destroy();
