You must set the text and classindex properties of the shapeObj for the
labels to appear as defined in the layer's classObj's (and styleObj's if
MS_VERSION >= 3.7). Example:

$shp = ms_newShapeObj(MS_SHAPE_LINE);
$shp->add($line); //$line is a valid LineObj
$shp->set('text',"MY LABEL");
$shp->set('classindex',0); // Important to choose the class this point
			   // will be rendered in. That's class 0 in
			   // $layer
$layer->addFeature($shp);
$layer->draw();
