How can a "Pager" mechanism be implemented in PHP to display images in batches of 100, similar to a gallery with multiple pages?

To implement a "Pager" mechanism in PHP to display images in batches of 100, you can use a combination of PHP and HTML to create a gallery-like interface with multiple pages. You can use PHP to retrieve the images from a directory, divide them into batches of 100, and display them on different pages using pagination links. 

<?php
// Get all image files from a directory
$images = glob('path/to/images/*.{jpg,jpeg,png,gif}', GLOB_BRACE);

// Calculate total number of images
$totalImages = count($images);

// Set images per page
$imagesPerPage = 100;

// Calculate total number of pages
$totalPages = ceil($totalImages / $imagesPerPage);

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

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

// Display images for the current page
for ($i = $start; $i < min($start + $imagesPerPage, $totalImages); $i++) {
    echo '<img src="' . $images[$i] . '" alt="Image ' . ($i + 1) . '">';
}

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