I think you should consider changing the way you write arrays. Instead
of using "$art60[][]", you could use "$art[60][][]". It also appears
that you mistyped the variable name in the "foreach" loop -- did you
mean to type "$alist[$num++][0]"? And why are you incrementing the
"$num" variable?

Nevertheless, there *is* a way to do this:

$varname = '$art' . $year; // Note the single quotes.
$alist = eval("return $varname;");

I don't recommend this, though. It's a security issue.
