Object property variable variable

[Hugh Oxford]

If I have an object property such as $obj->property_01 = 'blah'

how do I access it using another variable

$obj->fred = '01';

e.g. echo $obj->property_$ob j->fred
returns 'blah'

I've tried $obj->property_{$o bj->fred}

with no luck

It's not a terrible transparent construct, you might want to avoid this.
It looks like you could be better served having a property array and
accessing it like $obj->property[$obj->fred].

OTOH though, echo $obj->{'property_'.$ obj->fred} should work, I'd advise
against it.

$varName = 'property_' . (string) $obj->fred;
echo $obj->$varName


ensure the object property has public visibility.

Possibly a cleaner way is to use getter/setter methods and
call_user_func. ..just my opinion, though.

I agree with Rik...especiall y since it seems that you might be
iterating over the object to get the values of the properties. A
container (such as an array) is a better solution.

Good idea
