how do I move multiple times between the same page in PHP?

I am a PHP beginner and I am trying to write a facebook app that will ask a questionnaire for random friends.

I tried that for each friend a following info is presented in one page:

1. photo and name
2. questionnaire开发者_如何学Go + submit

But apparently, all random friends were shown together:

for ($i=1; $i<= $num_Of_Friends ; $i++){
    require('friendPhotoAndName.php');
    require('questannaire.php');

}

Can you please suggest me how to fix that?
