return from a script

[Anon]

How can I make a php script return a value (not to the client browser , but to the caller).
ex:
I want to call a php script from an ASP page,
<http://www.ibnetwork.com.br/getcolorname.php?color="FFFFFF">
this script should return "WHITE",
and this return should be available in a ASP variable !!

Something like this, maybe?

<?php
if ($color == "FFFFFF") { $ret_color = "WHITE"; }

header("Location: $HTTP_REFERRER?ret_color=$ret_color\n");
?>

Add your own color logic, of course, but that's about all you need. Then ASP should be able to access $ret_color in the query string.
