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? I see
switch, which is a little similar, but far from how it actually functions.
For those not familiar with the SELECT statement here is how I envision it
working in a PHP format similar to switch:
SELECT {
WHEN $Auth = 0:
WHEN $A = 1:
echo('$Aprint_list');
WHEN $B = 1:
echo('$Bprint_list');
WHEN $A = 2:
echo('$Aprint_list');
echo('$Aprint_list');
WHEN $B = 2:
echo('$Bprint_list');
echo('$Bprint_list');
DEFAULT:
}
The syntax may be a little off, but you get the picture. No breaks are
needed because it only performs the first match it comes to, then exits the
SELECT statement when finished the commands under that match. Putting a WHEN
statement with nothing to perform means exactly that, if this matches, do
nothing, then exit the SELECT statement. I hope that makes sense. The big
difference is you can put anything behind each WHEN statement as opposed to
looking at only the one variable like with switch. I am thinking I just need
to get creative with the switch or elseif commands, but thought I would ask
the list first if they had any better suggestions.
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;
}
