quick regular expression help

[webdev81]

Hi,

I'm trying to pick a value from a url.

url example 1
http://www.example.com/index.php?id=2123123

example 2
http://www.example.com/index.php?id=2123123&a=asdad

regular expression
preg_match("/id=(.*?)&¦\Z/",trim($url),$match);

this regular expression seems to work for the 2nd url but not for the first. if i replace the ¦ sign with? or just take the & sign out all togather then it works for the first URL.

Any help guys?

Thanks

if you simply want to ge the value of id or a, you can get them by
<?
$id = $_REQUEST['id'];
$a = $_REQUEST['a'];
?>

They are not a querystrings. The urls are stored in a DB.

Cheers!

$url_components=parse_url($url);
parse_str($url_components[query],$arguments);
$id=$arguments[id];
