How to develop the public platform by PHP after the user UnionID

how to jump to a page to display the user"s information page immediately after following Wechat"s public platform? At the same time, it also displays the information of the user UnionID! I would like to ask all the masters!

after Wechat follows, you can only call the official account home page. You can return a picture and text or a link message for users to click in and display it. It seems not possible to follow directly.
as for unnionid, you need an open platform and bind the official account to this open platform before you can get it.
