Setting '$layerObj->status=1' directly does not update the internal
MapServer data structures... you have to use

  $layerObj->set("status", 1);

or even better:

  $layerObj->set("status", MS_ON);

This applies to setting values in any of the MapScript objects in PHP.

I know this kind of sucks but unfortunately we're stuck with this
because of the way things work internally in PHP.  Last time I checked
there was still no way for a PHP module to have a callback or an event
trigerred when one of its class members was changed by the script... so
the only way around this is using the set() method.
