How can PHP be used to dynamically load and display the next set of images in a gallery when a user clicks on a "next" link?

To dynamically load and display the next set of images in a gallery when a user clicks on a "next" link, you can use AJAX to fetch the next set of images from the server without reloading the entire page. When the user clicks on the "next" link, an AJAX request is sent to a PHP script that retrieves the next set of images and returns them in JSON format. The JavaScript code then processes the JSON data and updates the gallery with the new images.

<?php
// gallery.php

// Get the page number from the AJAX request
$page = isset($_GET['page']) ? $_GET['page'] : 1;

// Query the database for the next set of images
$offset = ($page - 1) * 10;
$limit = 10;
$query = "SELECT * FROM images LIMIT $offset, $limit";
// Execute the query and fetch the images

// Return the images in JSON format
header('Content-Type: application/json');
echo json_encode($images);
?>
