Facebook posting on the wall/page with login using Facebook Connect

I want a PHP script that

1. logs into facebook with userid and password.
2. posts on the wall of a page.
3. Logs out.

Is it possible?

I am using php-sdk to post on the wall ri开发者_StackOverflowght now. But for that I have to log into my facebook account from the browser.

It violates facebook developers TOS.

The only possible way to authenticate user - is to use regular API and regular authentication form.

UPD:

You could ask offline_access permission from the user. After that you'll have permanent tokens and will be able to post any time you want.
