Not an RPG list, but your question is PHP-related more than it's RPG-related.

You don't need to "get creative" with anything as that's exactly how switch works if you have a break at the end of each case. So your example would look like so:
switch (true) {
case $Auth == 0:
break;
case $A == 1:
echo('$Aprint_list');
break;
case $B == 1:
echo('$Bprint_list');
break;
case $A == 2:
echo('$Aprint_list');
echo('$Aprint_list');
break;
case $B == 2:
echo('$Bprint_list');
echo('$Bprint_list');
break;
default:
break;
}
