Use this php class to create a sitemap for your site, or create a links menu.
The function is recursive, so it will read the content of the directories, and the subdirectories in them.

}
}
?>
To use the function you just need something like this :
<?php
$dir = new file2menu(‘/myDirectory’);
$dir->DisplayMenu();
You can also use the SaveAs method to save the menu in a file :
<?php
$dir = new file2menu(‘/myDirectory’);
$dir->SaveAs(‘FileToSave.html’);
