Dynamic point layer via mapscript

[Camden Daily]

Thanks for the replies!  It's working now.  I think the issue was with
when I was calling $image->draw.  It should be called before
$point->draw so that the point appears over the rest of the map (I
believe).

My revised and working code is as follows:

$layer = ms_newLayerObj($map);
$layer->set("name", "points");
$layer->set("type", MS_LAYER_POINT);
$layer->set("status", MS_DEFAULT);

$class = ms_newClassObj($layer);

$class->label->set("font", "arial");
$class->label->color->setRGB(255, 0, 0);

$style = ms_newStyleObj($class);
$symbol = $map->getSymbolByName("square");
$style->set("symbol", $symbol);
$style->set("size", 8);
$style->color->setRGB(255, 0, 0);

$image = $map->draw();

$point = ms_newPointObj();
$point->setXY($longitude, $latitude);
$point->draw($map, $layer, $image, 0, "test");

$image_url = $image->saveWebImage('MS_JPG', 1, 1, 0);
