Dylan, Here is some sample code from one of our apps here at PSU. I hope 
it is useful,
Percy

//start sample code
     $cities=ms_newLayerObj($map);
     $cities->set("name", "Cities");
     $cities->set("data", "all_cities_dissolved");
     $cities->set("type", MS_LAYER_POLYGON);
     $cities->set("status", MS_OFF);
     $cities->set("transparency", 20);
     $cities->set("classitem", "NAME");
     $cities->setProjection($projection);
     //next few lines are to enable querry
     $cities->set("group", "Selectable Layers");
     $cities->setMetaData("Description", "City");
     $cities->setMetaData("Result_Fields", "NAME");
     $cities->setMetaData("Group", "Selectable Layers");
     $cities->setMetaData("Layer", "cities");

     $class_cities_lrg=ms_newClassObj($cities);
     $class_cities_lrg->set("name", "Large Cities");
     $class_cities_lrg->setExpression("/Metro Area/");
     $class_cities_lrg->set("maxscale", 10000000);
     $class_cities_lrg->set("minscale", 5000001);
     $style_cities_lrg=ms_newStyleObj($class_cities_lrg);
     $style_cities_lrg->color->setRGB(255,255,255);
     $class_cities_lrg->set("template", "ttt_query.html");

     $class_cities_med=ms_newClassObj($cities);
     $class_cities_med->set("name", "Medium & Large Cities");
     $class_cities_med->setExpression("([AREA] > 0.01)");
     $class_cities_med->set("maxscale", 5000000);
     $class_cities_med->set("minscale", 500001);
     $style_cities_med=ms_newStyleObj($class_cities_med);
     $style_cities_med->color->setRGB(255,255,255);
     $class_cities_med->set("template", "ttt_query.html");
//end sample code
