Quick (and easy) PHP question

I know for you guys this should be easy...

Looked all over and I can't find it :-(

Here's a PHP script I need (it's easy).....

User comes to www.abc.com/index.html?keyword=sxtmak

I need user to go to www.xyz.com/index.html?subid=sxtmak

Another example....

User comes to www.xyz.com/index.html?keyword=product245

I need user to go to www.sas.com/index.html?subid=product245

I used to have the PHP script to redirect for this kinda thing, but I lost it along with a server crash!!! Could a nice soul whip this up for me?

Thanks and God bless in advance!!!

 

Got it!!

<?php

header("location: http://www.outgoingurl.com?subid=".$_GET['keyword']);
exit();

?>

 

You may want to add

header("HTTP/1.1 301 Moved Permanently");

before that.
