How can PHP be used to display a larger image when a thumbnail is clicked on?

To display a larger image when a thumbnail is clicked on, you can use PHP to dynamically load the larger image based on the thumbnail that was clicked. This can be achieved by using JavaScript to handle the click event on the thumbnail and then passing the image URL to a PHP script that will load and display the larger image. 

```php
<?php
if(isset($_GET['image'])) {
    $image = $_GET['image'];
    echo '<img src="' . $image . '" />';
}
?>
```

In this code snippet, we check if an 'image' parameter is passed in the URL. If it is, we retrieve the image URL and display it using an `<img>` tag. This code can be used in conjunction with JavaScript to pass the image URL when a thumbnail is clicked.
