variables variables

[Anon]

I'm back!!!!!!!!!!!!

I have a small problem hoping you can help!

I have used variables variables to solve one problem and thought I could use it again for this problem.

I want to concatenate all my variables and test if they = "".

Here's where I stand:

for ($id = 1 ; $id <= 2 ; $id++)
{
$ans[] = "\$gift_".$id;
}
$junk = implode(".",$ans);

which results in

$junk= $gift_1.$gift_2

test the variable called junk against some logic like:
if ($pledge_amount == "" or
($pledge_amount >= "80" && $send_gift == "1" && $junk == "")

do something!

Any thoughts!

$junk = "";
for ($id = 1 ; $id <= 2 ; $id++)
{
$junk .= ${"gift_".$id};
}

if ($pledge_amount == "" || ($pledge_amount >= "80" && $send_gift == "1" && $junk == "")

Touchdown!

Thank you!
