如何使用PHP将关键字传递到登录页面？

Question

I'm using a landing page to redirect to my tracking url, how do I pass the keyword to my landing page which then passes it to my tracking link? Here is what my tracking link ends with:

&keyword={keyword}

I have tried doing http://www.foo.com?keyword={keyword} but no luck.

My landing page has this code:

<?php

header("Location: http://trackinglink.com&keyword={keyword}");

exit;
?>

Help please!!

edit: sorry for not being clear, I'm doing PPC and I need to use a landing page instead of direct linking (tracking url) so I need to be able to pass the keyword from the lander (which I'm gonna give to the PPC network) to my tracking link so I can see what keywords convert.

I need to know how to format the url to pass the keyword and what code to put into the landing page. thanks.

Answer 1

either the below, or I am not sure what you've asked at all

<?php

$keyword = 'location'; 

header("Location: http://foo.com?keyword=".$keyword);

exit;
?>
