How can PHP be used to create pagination for displaying a limited number of images from a folder at a time?

When displaying a large number of images from a folder, it is important to implement pagination to limit the number of images shown at a time for better performance and user experience. PHP can be used to achieve this by reading the images from the folder, applying pagination logic to determine which images to display on each page, and then dynamically generating the HTML to show the images accordingly. 

<?php
// Define the folder containing images
$folder = 'images/';

// Get all images from the folder
$images = glob($folder . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

// Define number of images to display per page
$imagesPerPage = 10;

// Determine current page
$page = isset($_GET['page']) ? $_GET['page'] : 1;

// Calculate starting index for images
$start = ($page - 1) * $imagesPerPage;

// Slice the array of images based on pagination
$imagesToDisplay = array_slice($images, $start, $imagesPerPage);

// Display the images
foreach ($imagesToDisplay as $image) {
    echo '<img src="' . $image . '" alt="Image">';
}

// Pagination links
$totalPages = ceil(count($images) / $imagesPerPage);

for ($i = 1; $i <= $totalPages; $i++) {
    echo '<a href="?page=' . $i . '">' . $i . '</a> ';
}
?>
