In what scenarios would it be beneficial to use if statements in PHP to handle form submissions with predefined answers?

When handling form submissions with predefined answers in PHP, using if statements can be beneficial to validate user input against the predefined answers and take appropriate actions based on the input. This can help ensure that only valid responses are accepted and processed by the form. 

// Assuming a form submission with a predefined answer "Yes" and "No"
$user_input = $_POST['user_input'];

if ($user_input == "Yes") {
    // Process if user input is "Yes"
    echo "Thank you for selecting Yes!";
} elseif ($user_input == "No") {
    // Process if user input is "No"
    echo "Thank you for selecting No!";
} else {
    // Handle invalid input
    echo "Invalid input. Please select either Yes or No.";
}
