In linux I can schedule a wget to get several files via HTTP on a nightly basis.

Does Windows have a built in equivalent?

Thanks,

(I tried searching these forums but I got some bizarre forum error)

not built in, however you can get wget for windows:

then you can use the even scheduler to execute the commands at a specific time.

You could also do the same with the PHP. Wouldn't be too hard and using the scheduler it would do it nightly (or whenever).
