Matt,

This is only possible in the CVS MapServer.  See

http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=562

I'm not sure if it's fully implemented in the PHP Mapscript, but with
the Perl/Python/Ruby mapscript you'd do something like

     layer = mapobj.getLayerByName('copyright')
     layer.open()
     shape = layer.getShape(0)
     layer.close()

One solution you can try is to not define any inline features in your
map file, and then add the inline feature when needed.  This eliminates
the need to access an existing feature.

cheers,
Sean
