How can PHP serialization be utilized to store objects in sessions for better access?

Storing objects in sessions in PHP can be achieved by serializing the object before saving it to the session, and then unserializing it when retrieving it. This allows complex data structures to be stored and retrieved easily in sessions.

// Serialize the object before storing it in the session
$_SESSION['user'] = serialize($user);

// Retrieve the object from the session and unserialize it
$user = unserialize($_SESSION['user']);
