Store Object in PHP Session

// Start session
session_start();

// Create an object
class Person {
    public $name;
    public $age;
}

$person = new Person();
$person->name = "John";
$person->age = 30;

// Serialize the object
$serialized_person = serialize($person);

// Store the serialized object in the session
$_SESSION['person'] = $serialized_person;

// Retrieve the serialized object from the session
$serialized_person = $_SESSION['person'];

// Unserialize the object
$person = unserialize($serialized_person);

// Access the object properties
echo $person->name; // Output: John
echo $person->age; // Output: 30
In this example, we create a Person object, serialize it, store it in the session under the  person  key, retrieve it from the session, unserialize it, and access its properties.
