How can PHP be used to remember user selections and display relevant images without redirecting to new pages?

To remember user selections and display relevant images without redirecting to new pages, you can use PHP sessions to store the user's selections and dynamically load the relevant images based on those selections. This can be achieved by creating a PHP script that checks the session variables for user selections and then displays the corresponding images on the same page without requiring a redirect. 

<?php
session_start();

// Check if user has made a selection
if(isset($_POST['selection'])){
    $_SESSION['user_selection'] = $_POST['selection'];
}

// Define image paths based on user selection
$images = [
    'option1' => 'image1.jpg',
    'option2' => 'image2.jpg',
    'option3' => 'image3.jpg'
];

// Display selected image
if(isset($_SESSION['user_selection'])){
    $selected_image = $images[$_SESSION['user_selection']];
    echo '<img src="' . $selected_image . '" alt="Selected Image">';
}
?>

<!-- HTML form to allow user to make selections -->
<form method="post">
    <select name="selection">
        <option value="option1">Option 1</option>
        <option value="option2">Option 2</option>
        <option value="option3">Option 3</option>
    </select>
    <button type="submit">Submit</button>
</form>
