Variables

[Anon]

I got a problem with php and html-inputs. I have an input box (radio type), with questions to them. The questions do I fetch from my database with mysql --> Then I generate names to these tags as ans1, ans2, ans3,...and so on until the final question. My problem is then: what shall I do when I ask "are this variabel valued 1 or 2"? To get this general, I tried:
if ($ans.$id == 1) ... $id has the value 1,2,3...as many question I have. I want this variabel to check if I have marked 'yes' or 'no'. What shall I do?

So.

You have variables $ans1, $ans2, $ans3, ... , $ansx

Where $ans1 is Yes or No.

You want to loop through the answers?

for ($id = 1 ; $id <= iMaxIDs ; $id++)
{
$ans = "ans$id";
if ($$ans == "Yes") {}
else {}
}

I think should do the trick.

The $$ans means use the content of the variable $ans as a variable in its own right.

Good luck,
