Array call

Hi.
I have an included file with some arrays in there. For example i have the array $cat_dining with some staff in there.

When i call the page script.php?which=dining
i want to use the array that concats from "cat" + "$which"

However i can't seem to use the array.
I try to use a variable,
e.g $which_page = "cat".$which;
but apparently this is wrong

If i call the array directly like this "cat".$which , it still doesn't work.
How can i use the array according to the variable i get?

Thanks

John

I'm willing to bet that you have register_globals disabled, use the superglobal $_GET array instead.

$which = $_GET['which'];

The problem is not to get the variable $which.

The problem is to merge the $which with "cat" and produce a string that i can use it as the array.
If i use
print_r("cat".$which);
i get "cat_dining"

The string i get it but how can i use it as a predefined array?

What i tried and worked is to use variable variables.

I create a $tmp = "cat_".$which;
and then create $which_cat = $$tmp;

$which_cat now is the array $cat_dining

Please tell me if there is a better solution

${"cat_$which"};
