[Mapserver-users] no labels on dynamic layer

[James Jefferson]

You need to do an explicit drawLabelCache() call after completing your layer. 
I was mystified by this for quite a while.

For an example, see:
http://maps.aprsworld.net/mapserver/area/area.phps

Or the relevant snippet of code:
    $img = $GLOBALS["goMap"]->draw();

        createAPRSTrackLayer($db, $img);
        $GLOBALS["goMap"]->drawLabelCache($img);
    $url = $img->saveWebImage();
