I want to send my users to different pages based on user action. So I made multiple functions at the top of the page like so:

<?php

function one() {
     header("location: pagea.php");
}
function two() {
     header("location: pageb.php");
}
function three() {
     header("location: pagec.php");
}

?>

Of course I get an error because I am re declaring headers. At first I though it was going to be okay since I am containing them inside functions and am calling any one function at a time. But still I get the error. Is there any other way of doing this?
