Storing objects in PHP session

// Start the session
session_start();

// Define a class
class Person {
  public $name;
  public $age;
}

// Create an instance of the class
$person = new Person();
$person->name = "John";
$person->age = 30;

// Serialize the object and store it in the session
$_SESSION['person'] = serialize($person);

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

// Access the object properties
echo $person->name; // Output: John
echo $person->age; // Output: 30
