There's a number of things you can do with variable variables... they're
quite powerful, I like 'em a lot. :)
Anyway, you can do
<?php
$myvar2 = 'stuff';
$othervar = 2;
if (isset($myvar{$othervar}))
echo $myvar{$othervar};
?>
This would output
<snip>
stuff
</snip>
I think that's what you were asking... You've got to use the { and } around
the variables you're using to make teh variable variable.
