How can PHP be used to recursively read folder structures and generate dynamic image galleries?

To recursively read folder structures and generate dynamic image galleries in PHP, we can use a combination of directory iteration functions and HTML output generation. By iterating through the folders and files, we can dynamically generate HTML code to display the images in a gallery format on a webpage. 

<?php

function generateImageGallery($dir) {
    $files = scandir($dir);
    
    echo '<div class="image-gallery">';
    
    foreach($files as $file) {
        if ($file != '.' && $file != '..') {
            if (is_dir($dir . '/' . $file)) {
                generateImageGallery($dir . '/' . $file);
            } else {
                echo '<img src="' . $dir . '/' . $file . '" alt="' . $file . '">';
            }
        }
    }
    
    echo '</div>';
}

// Call the function with the root directory of your image files
generateImageGallery('path/to/your/image/folder');

?>
