Lets say i've passed a URL of www.wateva.com/test.php?user=$user from a php page that contained the variable $user with these codes.
so when they're taken to the test page they should see www.wateva.com/test.php?user=BobCode:$user = $_POST['username']; header ("location: test.php?user=$user");
Now...I wanna keep passing the variable of user and when I need it I want to be able to use that variable.
1st question: How do i pass the variable around in the URL from page to page?
2nd question: How do i use it later on, as in how do i assign it to a variable?
