         /* no debug output here */
         return msOGCWKT2ProjectionObj(wkt, self, MS_FALSE);
     }
+
+    int getUnits() {
+      return GetMapserverUnitUsingProj(self);
+    }
 }

Tried it with various different projections -> returns the unit types correctly. Sample:

nativeunits = ( mapscript.projectionObj(mapObj.getProjection()) ).getUnits()

[dmorissette]

Assigned to Alan to add this new projectionObj.getUnits() method to both SWIG and PHP MapScript, and update relevant docs.
