What are the potential pitfalls of using cookies to control PHP function execution?

Potential pitfalls of using cookies to control PHP function execution include security risks such as cookie tampering or injection attacks. To mitigate these risks, it is recommended to validate and sanitize cookie values before using them to control PHP function execution. 

// Validate and sanitize cookie value before using it
$function_to_execute = isset($_COOKIE['function']) ? filter_var($_COOKIE['function'], FILTER_SANITIZE_STRING) : '';

// Check if the function is allowed to be executed
$allowed_functions = ['function1', 'function2', 'function3'];
if (in_array($function_to_execute, $allowed_functions)) {
    // Execute the function
    $function_to_execute();
} else {
    // Handle unauthorized function execution
    echo "Unauthorized function execution";
}
