PHP/Mapscript - Layer Color

[Terry Wood]

Greetings,
    I am using PHP/Mapscript version 4.2.2 and I cannot figure out how
to change the color of a layer. If I filter an existing layer (with a
WHERE clause) I get output, but I cannot change the color of the layer
on the screen.

Here is a section of my code :

// Load Mapscript
dl("php_mapscript.so");

<>// Load MapServer .map file

<>$map = ms_newMapObj("/data/maps/hpWork.map");

// Query

$layer = ms_newLayerObj($map, $map->getLayerByName("Parcels"));

$layer->setFilter("parcelid IN ('0000-27-009-012-0-001-01','0000-14-008-008-0-001-01')");

$layer->set("status",MS_ON);

// Draw Map

$img = $map->draw();

$url = $img->saveWebImage();


I am not going to show all of my failed attempts at changing the layer
colors... Anybody know how to do this?
