Not an RPG list, but your question is PHP-related more than it's RPG-related. > Is there an equivalent command in PHP for the SELECT statement in RPG?

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; } -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/
