What are the limitations of using sessions and cookies for storing and accessing data in PHP, and what alternative solutions can be explored?

Using sessions and cookies for storing and accessing data in PHP has limitations such as security risks, limited storage capacity, and potential performance issues. An alternative solution is to use PHP's built-in session handling functions along with server-side storage options like databases or files. 

// Using PHP's built-in session handling functions with server-side storage

// Start the session
session_start();

// Store data in the session
$_SESSION['user_id'] = 123;

// Retrieve data from the session
$user_id = $_SESSION['user_id'];
