If I understand your question properly I'd explode $two_vars with
whatever seperator you have between them and then you'll need to use
eval to get your results. Maybe something like...
$dbVars=explode(',',$two_vars); // Assuming comma seperator
foreach($dbVars AS $key => $value) {
$eval="\$temp=".$value.";";
eval($eval);
echo $temp;
}
