I did a quick search and found an old ticket relating to that:
  http://trac.osgeo.org/mapserver/ticket/762

... then I started to wonder why we never implemented removeLayer(), and 
it came back to me that removeLayer() returns a standalone layerObj 
that's decoupled from the mapObj and can even be reinserted into the map 
at another location later on with insertLayer(). Without looking into 
this in any detail, it sounds like adding this may be more involved than 
just adding a new method since PHP MapScript doesn't allow decoupling 
objects like this at the moment. That and the fact that there are 
simpler alternatives to do the same thing (i.e. setting status 
MS_DELETE) probably explains why we never did it.

In which case does setting the status to MS_DELETE not work? That should 
work for rendering, querying, etc.
