Storing current url in a variable

[kkonline]

I want to store the current page url in variable $link

I used

$link=$_SERVER['PHP_SELF'];

But it gave me only pages.php if the current link is [url]http://www.example.com/pages.php?catid=1&id=3[/url]

This is required as i am storing the url in a social bookmarking site

What to do?

[edit reason] Use example.com, thanks. [/edit]

take a look at the $_SERVER [php.net] vars and see which one will work for you
