What is the recommended method for storing arrays in cookies in PHP?

When storing arrays in cookies in PHP, it is recommended to serialize the array before setting it as a cookie value. This ensures that the array data is properly encoded and can be easily retrieved and unserialized when needed. 

// Serialize the array before storing it in a cookie
$array = [1, 2, 3];
$serializedArray = serialize($array);
setcookie('myArray', $serializedArray, time() + 3600, '/');

// Retrieve and unserialize the array from the cookie
if(isset($_COOKIE['myArray'])) {
    $unserializedArray = unserialize($_COOKIE['myArray']);
    print_r($unserializedArray);
}
