In what scenarios would using a recursive function in PHP for directory traversal be more advantageous than alternative methods?

Using a recursive function in PHP for directory traversal is advantageous when you need to traverse through nested directories of unknown depth. This approach simplifies the code by allowing you to handle all subdirectories within a single function call, making it easier to manage and maintain. Additionally, recursive functions can handle dynamic directory structures without the need for hardcoding specific levels of nesting.

function traverseDirectory($dir){
    $files = scandir($dir);
    
    foreach($files as $file){
        if($file != '.' && $file != '..'){
            if(is_dir($dir.'/'.$file)){
                traverseDirectory($dir.'/'.$file);
            } else {
                echo $dir.'/'.$file . "\n";
            }
        }
    }
}

traverseDirectory('/path/to/directory');
