[Mapserver-users] can I use different symbols in thesamedynamiclayer?

Hi Vinko,

Okay but only useful when there's no need to colorize the different
symbols. ;-)
Let's leave it at that.

YES! Success at last. *bg* Thank you very much! 

Even if this gets slowly off topic - if you will excuse me - what's
wrong with $newclass->label=$originalclass->label;

I must have a wrong understanding of the class-handling in
PHP/MapScript. I thought I could transfer the whole sub-class (member)
e.g. the label with all it's attributes set to another class. At least
when I use a class in a class with pure PHP such operations are no
problems, the sub-class with all it's attributes is given to the new
class.

But this way doesn't spare handling with one individual class per
symbol, does it? I think I missed the advantage.
