Is it recommended to use sessions or re-instantiate objects for each request in PHP?

It is recommended to use sessions in PHP for maintaining user data across multiple requests, rather than re-instantiating objects for each request. Sessions provide a way to store user-specific information securely on the server side and can be accessed and updated throughout the user's session. Re-instantiating objects for each request can lead to unnecessary overhead and can result in losing important data between requests. 

// Start a session
session_start();

// Store user-specific data in the session
$_SESSION['user_id'] = 123;

// Access user-specific data from the session
$user_id = $_SESSION['user_id'];
