What resources or tutorials are recommended for learning more about working with directory structures in PHP?

When working with directory structures in PHP, it is recommended to familiarize yourself with PHP's built-in functions for handling directories, such as opendir(), readdir(), and closedir(). Additionally, resources like the PHP manual and online tutorials can provide further guidance on how to effectively navigate, create, and manipulate directories in PHP. 

// Example code snippet for listing files in a directory
$dir = './path/to/directory';

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
        }
        closedir($dh);
    }
}
