What is the recommended way to store $_POST variables in $_SESSION in PHP?

When storing $_POST variables in $_SESSION in PHP, it is recommended to sanitize the input data to prevent any security vulnerabilities. This can be done by using functions like filter_input() or htmlentities() to clean the data before storing it in the session. Additionally, it is important to only store necessary data in the session to avoid potential security risks. 

// Sanitize and store POST variables in SESSION
foreach ($_POST as $key => $value) {
    $_SESSION[$key] = htmlentities($value);
}
