Ok. As I see from conversation, you want to get values, which depends on radio.
You can do it this way:
foreach ($graphEdge as $graphNode) {
echo
"";
echo "";
echo "";
}
And then you can get selected values by radio value like this (let's suppose your form sends POST request):
$profile = $_POST['fb_profile'];
$accessToken = $_POST['fb_access_token'][$profile];
$id = $_POST['fb_id'][$profile];
