Variable inside Variable?

[sKunKbad]

I need $count to be inside $_POST['Q$count'] as in the following, but its not working.

 

++$count;

echo "For question # $count, \"<em>" .$question->q. "</em>\", your answer was {$_POST['Q$count']}.<br />";

 

I've tried a few different things, but can't get it done. What am I doing wrong here?

 

Thanks.

$_POST['Q'.$count]

or

$_POST["Q$count"]

or

$_POST["Q".$count]

...

ok I figured it out on my own:

 

++$count;
$num = "Q$count";
$qnum = $_POST[$num];
echo "For question # $count, \"<em>" .$question->q. "</em>\", your answer was $qnum.<br />";
