What are the potential security risks of faking cookies as a user in PHP?

Faking cookies as a user in PHP can lead to security risks such as unauthorized access to sensitive information, session hijacking, and manipulation of user data. To mitigate these risks, developers should validate and sanitize all incoming cookie data before using it in their application. 

// Validate and sanitize incoming cookie data
$cookie_value = isset($_COOKIE['cookie_name']) ? filter_var($_COOKIE['cookie_name'], FILTER_SANITIZE_STRING) : '';

// Use the sanitized cookie value in your application
echo "Welcome back, " . $cookie_value;
