What are some best practices for creating a gallery with thumbnails and links to larger images in PHP?

When creating a gallery with thumbnails and links to larger images in PHP, it's important to organize your images in a directory structure that makes it easy to retrieve and display them dynamically. You can use PHP to scan the directory for images, generate thumbnails, and create links to the larger images. It's also a good practice to use CSS to style the gallery and ensure that it is responsive. 

<?php
// Directory where images are stored
$directory = 'images/';

// Get all files in the directory
$files = scandir($directory);

// Display thumbnails and links to larger images
foreach ($files as $file) {
    if (in_array(pathinfo($file, PATHINFO_EXTENSION), array('jpg', 'jpeg', 'png', 'gif'))) {
        echo '<a href="' . $directory . $file . '" target="_blank"><img src="' . $directory . 'thumbnails/' . $file . '" alt="Thumbnail"></a>';
    }
}
?>
