In PHP, what is the recommended approach for displaying the next image after a question has been answered in a quiz format?

When displaying a quiz format where each question is followed by an image, the recommended approach for displaying the next image after a question has been answered is to store the image URLs in an array and keep track of the current question number. After the user answers a question, increment the question number and use it to access the next image URL from the array to display. 

<?php

// Array of image URLs
$images = [
    'image1.jpg',
    'image2.jpg',
    'image3.jpg',
];

// Get the current question number
$currentQuestion = isset($_GET['q']) ? $_GET['q'] : 0;

// Display the question
echo "Question " . ($currentQuestion + 1) . ": What is the answer?";

// Display the image
echo "<img src='" . $images[$currentQuestion] . "' alt='Image for question " . ($currentQuestion + 1) . "'>";

// After the question is answered, increment the question number
$newQuestion = $currentQuestion + 1;

// Display a link to the next question
echo "<a href='quiz.php?q=$newQuestion'>Next Question</a>";

?>
