PHP Mapscript - Unable to add a style object to label object

[khaitang]

There is currently no way to add a style to a label using MapScript? with MapServer 6.x. Basically the equivalent MapScript? code for this .map file label declaration is not available:

LABEL
  FONT "arial"
  TYPE truetype
  ENCODING 'UTF-8'
  SIZE 14
  COLOR 200 200 200
  POSITION AUTO
  POSITION CC
  OFFSET 0 0
  PARTIALS TRUE
  BUFFER 6
  STYLE
    GEOMTRANSFORM LABELPOLY
    OUTLINECOLOR 40 40 40
    WIDTH 12
  END
END
