Nelson, Here is some sample PHP/Mapscript code from one of our apps here
at PSU. Others have found it useful, I hope you do, too :-)
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

> Hi all,
>
> I have a site that uses mapserver wms to generate tiles which overlay
> on top of a google map. I would like to make the mapserver tiles
> user-customizable, so that the wms call can return a map that
> reflects a query (for example a map that shows several but not all of
> the species in the postgre database, or just records from specific
> years). The reason I am overlaying the mapserver tiles on the google
> map is that we have too many points for the google api to plot, and
> it is much faster this way.

> Can php/mapserver be used to generate custom wms such as this? If
> so, is there a good tutorial on how to do it?
>
> If not, does anyone have any better suggestions of how to generate
> customized wms layers from a postgre database?
