What are the best practices for handling and storing large amounts of data in PHP sessions?

When handling and storing large amounts of data in PHP sessions, it is important to be mindful of the limitations of server memory and session storage. To optimize performance and prevent potential issues, consider storing only essential data in the session and offloading larger data to a database or file system. Additionally, use efficient data structures like arrays or serialized objects to minimize the size of session data. 

// Example of storing large data in a session
session_start();

// Only store essential data in the session
$_SESSION['user_id'] = 123;

// Offload larger data to a database or file system
$largeData = ['key1' => 'value1', 'key2' => 'value2'];
file_put_contents('large_data.txt', serialize($largeData));
