I have this script, which works perfectly well. BUT I will end up creating hundreds of variations if I keep doing it this way.

```
    <?php

$q1 = $_GET["q1"];
$q2 = $_GET["q2"];
$q3 = $_GET["q3"];
$q4 = $_GET["q4"];

if ( $q1 == "a" && $q2 == "a" && $q3 == "a" && $q4 == "a" ) {
    header("Location: http://www.mostly-a.co.uk");
    exit;    
}

if ( $q1 == "b" && $q2 == "b" && $q3 == "b" && $q4 == "b" ) {
    header("Location: http://www.mostly-b.co.uk");
    exit;    
}

?>

```

Basically I need the script to echo 1 of 5 possible urls based on which answers are given

So for example, "url-mostly-a" would be echo'd if the user selected:
aaaa
aaab
aaba
abaa
baaa
aaac
aaca
acaa
caaa

etc etc.....
