Catch the URL

[sqlnew]

I need use the URL as the key for one of my table, how can I catch the URL of the page the user visiting? Which variable of $_SERVER should I use?

Thanks.

there are a bunch

try this and see which form works for you

echo '<pre>';
print_r($_SERVER);
echo '</pre>';

[sqlnew]

Thank you very much. Now I know how to get the URL by combining some of the variables.
Thanks again.
