PHP get question

[wibumba]

I'm making my php script display a page based on a get variable. I know I can do this by (for instance) "index.php?page=pics", but I remember seeing a script a month ago (I forget which site and how I found it) that retrieved a value from a URL like this "index.php?pics". How exactly would I do that?

You can parse $_SERVER['QUERY_STRING'], or alternatively (less flexible) simply check for isset($_GET['pics']).

Ah yes, that's the one. Thanks.

Oh, perhaps better than parsing QUERY_STRING:
$s = array_keys($_GET); // PHP doesn't allow us to do array lookup without an intermediate variable.
$s = @$s[0];
