Mapscript adding class with PHP

Bart !

That clearifies a lot. I didn't know i could save the mapfile.

The problem was that my new class was the last one in the layer. It  
was after:

CLASS
       NAME "Other Countries"
       EXPRESSION ('[NAME]' ne 'Canada')
       METADATA
       END
       STYLE
         ANGLE 360
           COLOR 200 200 200
           OUTLINECOLOR 100 100 100
         SYMBOL 0
       END
       STYLE
         ANGLE 360
           COLOR 100 100 100
           OUTLINECOLOR 255 255 255
         SYMBOL 0
       END
     END

So i added in php:

$this_layer->moveclassup(2);

Then i changed the expression of the Other Countries Class

$myclass = $this_layer->getClass(2);
$myclass->setExpression("(('[NAME]' ne 'Canada') AND ('[NAME]' ne  
'Chad'))");

That was it. Thanks a lot !
