How can PHP be used to create interactive quizzes for web designers?

To create interactive quizzes for web designers using PHP, you can store the quiz questions and answers in a database, retrieve them using PHP, and dynamically generate the quiz interface for users to interact with. You can also use PHP to handle user input, check answers, and calculate scores. 

<?php
// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "quiz_db";

$conn = new mysqli($servername, $username, $password, $dbname);

// Retrieve quiz questions from database
$sql = "SELECT * FROM questions";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Question: " . $row["question"]. "<br>";
        echo "Answer: " . $row["answer"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
