Need a php/mapscript example...

[Camden Daily]

assuming you want to do this in php/mapscript...

// create our map object
$map_file = "chicago.map";
$map = ms_newMapObj($map_file);

// create a temp layer to hold our points
$point_layer = ms_newLayerObj($map);
$point_layer->set("name", "markers");
$point_layer->set("type", MS_LAYER_POINT);
$point_layer->set("status", MS_DEFAULT);

// create a class and style for this layer
$point_class = ms_newClassObj($point_layer);
$point_style = ms_newStyleObj($point_class);
$point_symbol = $map->getSymbolByName("point");
$point_style->set("symbol", $point_symbol);
$point_style->set("size", $marker_size);

// draw our image without the points
$image = $map->draw();

// initialize our point and add it to the map
$point = ms_newPointObj();
$point->setXY($longitude, $latitude);
$point->draw($map, $point_layer, $image, 0, "");

(do the above section for each point, or wrap it in a function)

// get the location for our new image
$image_url = $image->saveWebImage('MS_JPG', 1, 1, 0);
