A very simple way to display the folder structure is to use the RecursiveTreeIterator class (PHP 5 >= 5.3.0, PHP 7) and generate an ASCII graphical tree.

$it = new RecursiveTreeIterator(new RecursiveDirectoryIterator("/path/to/dir", RecursiveDirectoryIterator::SKIP_DOTS));
foreach($it as $path) {
  echo $path."
";
}

You can also have some control over the ASCII representation of the tree by changing the prefix using RecursiveTreeIterator::setPrefixPart, such as $it->setPrefixPart(RecursiveTreeIterator::PREFIX_LEFT, "| ");

function listFolderFiles($dir){
    $ffs = scandir($dir);

    unset($ffs[array_search('.', $ffs, true)]);
    unset($ffs[array_search('..', $ffs, true)]);

    // prevent empty ordered elements
    if (count($ffs) < 1)
        return;

    echo '';
    foreach($ffs as $ff){
        echo ''.$ff;
        if(is_dir($dir.'/'.$ff)) listFolderFiles($dir.'/'.$ff);
        echo '';
    }
    echo '';
}

listFolderFiles('Main Dir');
