How can PHP functions be utilized to dynamically include multiple files based on a specified directory structure?

To dynamically include multiple files based on a specified directory structure in PHP, you can use functions like `scandir()` to scan the directory for files and `include()` or `require()` to include them dynamically. By iterating over the files in the directory, you can include each file as needed.

$directory = 'path/to/directory';
$files = scandir($directory);

foreach($files as $file) {
    if(is_file($directory . '/' . $file)) {
        include($directory . '/' . $file);
    }
}
