How can PHP be used to create a quiz where the ID increases with each button click?

To create a quiz where the ID increases with each button click in PHP, you can use a session variable to keep track of the current question ID. Each time the button is clicked, you can increment the session variable to move to the next question. This way, you can dynamically display different questions based on the current question ID. 

<?php
session_start();

// Initialize question ID
if (!isset($_SESSION['question_id'])) {
    $_SESSION['question_id'] = 1;
}

// Check if button is clicked
if (isset($_POST['next_button'])) {
    $_SESSION['question_id']++;
}

// Display current question based on question ID
$question_id = $_SESSION['question_id'];
echo "Question ID: $question_id";

// Display the rest of your quiz content here
?>
