How can PHP be used to display images step by step with a button click?

To display images step by step with a button click using PHP, you can store the image paths in an array and use a session variable to keep track of the current image being displayed. When the button is clicked, increment the session variable to display the next image in the array. 

<?php

session_start();

$images = array('image1.jpg', 'image2.jpg', 'image3.jpg');
$currentImage = isset($_SESSION['currentImage']) ? $_SESSION['currentImage'] : 0;

if(isset($_POST['next'])) {
    $currentImage = ($currentImage + 1) % count($images);
}

$_SESSION['currentImage'] = $currentImage;

echo '<img src="' . $images[$currentImage] . '" alt="Image">';

?>

<form method="post">
    <input type="submit" name="next" value="Next Image">
</form>
