What are the potential pitfalls of storing POST and GET variables in a BLOB for session management in PHP?

Storing POST and GET variables in a BLOB for session management in PHP can lead to security vulnerabilities such as SQL injection attacks and data manipulation. To mitigate these risks, it is recommended to use PHP's built-in session management functions to securely store and retrieve session data. 

// Start a secure session
session_start();

// Store POST and GET variables in session variables
$_SESSION['post_data'] = $_POST;
$_SESSION['get_data'] = $_GET;

// Retrieve POST and GET variables from session
$post_data = $_SESSION['post_data'];
$get_data = $_SESSION['get_data'];
