PHP/HTML/Javascript: Automatically leave page?

Question

I've written a some PHP that interacts with a SQL database and is just around as an intermediate between two pages.

I want a user to automatically be forced to leave that page and move to another (or even a back to previous page function)

What is the easiest way to do this? I'm happy to use PHP, HTML, or JavaScript to do it.

From php you can use the header() function to change the location:

header("Location: newpage.html");

Just be aware that if you're using header, you can't emit any html or whitespace before you make this call unless you're buffering output. Doing so will cause warnings to the effect that headers have already been sent (there is a way to work around this).
