php mapscript + .map file question (color specific country)

[Geoff Rowland]

I don't quite understand how to do this.

I have a shp file of Africa.  Based on user selection, I want to 'zoom'
to the selected country - color that country a specific color and all
its neighbors a different color.  I can set the extents of the country
based on user selection with no problem. However I am unsure how to set
the color of the country that was selected.  Any help would be great!
Attribute name in the shape file is Cntry_name

here is my map file

NAME "Africa"
