Mapscript adding class with PHP

[Arie Mijnlieff]

Hi Murat !

No this doesnt solve the problem:

PHP Fatal error:  Call to a member function on a non-object in /var/ 
www/html/mapdemo/bulgaria/test.php on line 13

color is not an attribute of the class object.. Maybe i should try to  
define a new layer with php for each country that i would like to  
paint..

Thanks for your suggestion !
