parsing variables in URL

[Anon]

I have a hyperlink, "more..." in each row of a multi row table. Selecting the link in each row generates a distinct target URL,

(I cannot use post and make this a form button instead of a hyper link)

http://www.detroitcircle.com/cgi-bin/sample.php?id=1

http://www.detroitcircle.com/cgi-bin/sample.php?id=2

http://www.detroitcircle.com/cgi-bin/sample.php?id=3
...
...
...
...
...

Now, how can I read the distinct id(1, 2, 3...) at the end of each url into a variable in the target fiel sample.php

Can someone please give me some ideas.

Thanks

It should already be available to you as $id. If not (gpc processing is maybe turned off) you can always access it via the global array $HTTP_GET_VARS
i.e. $HTTP_GET_VARS['id']). Don't forget that if you are trying to access these from inside a function, you must declare variable global--this applies to arrays like $HTTP_GET_VAR too.
