Question: is it possible to redirect a visitor on my php page as soon as I received a Postback/Callback? If yes can someone provide me some pointers where to start. Searched in Google for it but found nothing... 

Thanks!

Answer: 
I believe you are looking for include?

```
"ab123de".include?("123")

```
