Calling variable using variable name....

[rocketchef]

Hi,

I'm building a quiz online, and I want to call the correct answer to a quiz.

$correct[$i] is a number 1-3

$answer1[$i], $answer2[$i], $answer3[$i] are answers, one of which is correct.

Bearing is mind these are all in arrays, how can I call $answerX[$i] based on $correct[$i]?

I thought it would be something like this:
$answer{$correct[$i]}[$i]

I can't find the syntax for this, ideas appreciated.

Try it

${answer.$correct[$i]}[$i]

Why don't you store your answers in:

$answer[$i][1],
$answer[$i][2],
$answer[$i][3]

and read the right one with:

$answer[$i][$correct[$i]]

?
