how to parse part of url then insert into rest of the links?

I'm trying to build a little script that does that following...

Affiliate has an url like this: http://www.site.com/pro.php?id=123

rip the the 123, save it into a variable.

insert that variable to all the links on the page.

can someone help me write that? I haven't programmed anything for years, the last language I learned asp and I pretty much forgot all of it. This should be incredibly easy though, right?

thanks

 

No need to 'rip' it.

$aff_id = $_GET['id'];

$unprepared_link = "http://www.yoursite.com/home.html";
$prepared_link = $unprepared_link . '?id=' . $aff_id;

PHP:

 

thanks a ton!
