Does anyone have a script that can autologin and scrap email ids of friends of several accounts.

I can write the scrap part. but i need to know how to do the autologin for serveral accounts one by one. I am trying to do in php.

if anyone know any tool that can scrap all friends ids of several accounts, that would be super great

thanks alot
