just look over the php functions used. the guts of it are here:

>>>> chdir($wd);
notice, i use GLOB_BRACE...look in the manual for why and you'll be golden.
as for directory recursion, let me know if you get stuck. is_dir() will help
as a hint...but you'll probably find many examples just by googling.
