In what ways can PHP code be improved to enhance the user experience in a quiz format, such as providing feedback on correct or incorrect answers?

One way to enhance the user experience in a quiz format is to provide feedback on correct or incorrect answers. This can be achieved by implementing conditional statements in the PHP code that check the user's input against the correct answer and display appropriate feedback messages.

<?php
$correct_answer = "B"; // Assuming the correct answer is option B

if(isset($_POST['submit'])){
    $user_answer = $_POST['answer']; // Assuming the user's answer is submitted via a form input field with name 'answer'

    if($user_answer == $correct_answer){
        echo "Correct answer! Well done!";
    } else {
        echo "Incorrect answer. Try again!";
    }
}
?>
