What are some potential pitfalls of using a status variable in PHP for controlling the processing of user inputs?

One potential pitfall of using a status variable in PHP for controlling the processing of user inputs is that it can be prone to manipulation by malicious users. To mitigate this risk, it is important to validate and sanitize user inputs before setting the status variable. Additionally, using a secure session management technique can help prevent unauthorized access to the status variable. 

// Validate and sanitize user input before setting the status variable
$user_input = $_POST['input'];
$validated_input = filter_var($user_input, FILTER_SANITIZE_STRING);

// Use a secure session management technique to prevent unauthorized access to the status variable
session_start();
$_SESSION['status'] = $validated_input;
