Yes this can be done with Mapscript. Unfortunately I'm not sure of the
PHP syntax, but here is a Perl Mapscript example. The trick here is
getting an image object and doing the drawing yourself using
pointObj->draw().

my $map = new mapscript::mapObj("simple_points.map");
# create an image for drawing.
my $img = $map->draw();
my $layerObj = $map->getLayerByName('points');
my $point = new mapscript::pointObj();
$point->{x} = $longitude;
$point->{y} = $latitude;
my $label =  "The label";
$point->draw($map, $layerObj, $img, undef, $label);
# To display labels.
$map->drawLabelCache($img);
$img->save("/tmp/map.png");
