What is the purpose of using a token in PHP for status tracking?

Using a token in PHP for status tracking allows for secure and efficient monitoring of a user's progress through a multi-step process or transaction. By assigning a unique token to each user session, the status can be easily tracked and updated as the user moves through different stages. This helps in maintaining data integrity, preventing unauthorized access, and providing a seamless user experience.

php 
// Generate a unique token for status tracking
$token = md5(uniqid(rand(), true));

// Store the token in a session variable
$_SESSION['status_token'] = $token;

// Retrieve the token for status tracking
$token = $_SESSION['status_token'];
