What is the best way to display a gallery with 4 thumbnails per page and a detail view of each entry in PHP?

To display a gallery with 4 thumbnails per page and a detail view of each entry in PHP, you can use a combination of HTML, CSS, and PHP. You can create a loop to iterate through your gallery entries and display 4 thumbnails per page. When a thumbnail is clicked, you can show the detail view of that entry. You can use PHP to dynamically generate the gallery content based on your data source.

<?php
// Sample gallery data
$gallery = array(
    array('image' => 'image1.jpg', 'title' => 'Entry 1', 'description' => 'Description for Entry 1'),
    array('image' => 'image2.jpg', 'title' => 'Entry 2', 'description' => 'Description for Entry 2'),
    array('image' => 'image3.jpg', 'title' => 'Entry 3', 'description' => 'Description for Entry 3'),
    array('image' => 'image4.jpg', 'title' => 'Entry 4', 'description' => 'Description for Entry 4'),
    // Add more entries as needed
);

// Display 4 thumbnails per page
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$perPage = 4;
$start = ($page - 1) * $perPage;
$end = $start + $perPage;

echo '<div class="gallery">';
for ($i = $start; $i < $end && $i < count($gallery); $i++) {
    echo '<a href="?page=' . $page . '&entry=' . $i . '"><img src="' . $gallery[$i]['image'] . '" alt="' . $gallery[$i]['title'] . '"></a>';
}
echo '</div>';

// Display detail view of the selected entry
if (isset($_GET['entry'])) {
    $entry = $gallery[$_GET['entry']];
    echo '<div class="detail-view">';
    echo '<h2>' . $entry['title'] . '</h2>';
    echo '<img src="' . $entry['image'] . '" alt="' . $entry['title'] . '">';
    echo '<p>' . $entry['description'] . '</p>';
    echo '</div>';
}
?>
