[GRASSLIST:13] grass raster on php_mapscript

[Simone Pittaluga]

Hi
i have a problem with drawing a grass raster with php mapscript.
When i try to draw a layer with grass raster the output is a white image. If 
i add a layer with a shape file, mapscript draw the shape file but not the 
grass raster file.
i have already a mapserver CGI working on the same grass data and it works 
fine.
there is somebody help me to draw a grass raaster with mapscript?
Thanks
