Why this variables $_SESSION['username'] and $username are interfering

[centenond]

In local host i could create $username and $_SESSION['username'] and were two different variables, now it seems to interfere?

1) both are different

2) one is $username is local page variable and $_SESSION['username'] is a session variable and its an array too.

3) even $UserName, $userName, $_SESSION['uSERnAME'], $_SESSION['UserName'] all are different as php is case sensitive

4) any $_SESSION variable is available globally across all pages if you start your page with session_start(); function

5) other variables stay live for that particular page only

Yes, im aware of all this, but for some reason $username is changing $_SESSION['username'] variable... $id is changing $_SESSION['id'] value.. etc, as i said before , in localhost it was working perfectly fine... when i pass it all to ipage the problem starts..

thanks for reply
