I have form values stored in an object.

I have a set of numbered form fields:

specialty1
specialty2
specialty3

I need to loop through these, check for content and process accordingly. I
can't figure out how to correctly concatenate the number to the end of the
field name. For example:

for ($i = 1; $i <= 3; $i++) {
if (eval("$node->specialty" . $i)) {
//do something
}
}
I know eval is slow, but what other options are there?

Thanks.
