[mapserver-users] PHP MapScript - Remove Layer labelitem/classitem

[Geo-6]

Hi everyone, 

Probably a stupid question but I can't figure it out : 

I open a Layer through " $map->getLayer() " and I want to remove "
labelitem " and " classitem" parameters.

I tried to set these parameters to NULL " $layer->labelitem = NULL; " or
" $layer->set('labelitem', NULL); " and to empty " $layer->labelitem =
''; " or " $layer->set('labelitem', ''); " but it doesn't remove the "
LABELITEM " in the " LAYER " in the MapFile when I save the MapFile "
$map->save() ". 

I found that setting an int/double parameter to -1 value removes it
(like " maxscaledenom " or " minscaledenom "). 

How can I remove " labelitem " / " classitem " parameters ? 

Thanks a lot for your help ! 

MapFile before MapScript : 

LAYER
 NAME "test"
 CLASSITEM "myclasscolumn"
 LABELITEM "mylabelcolumn"
 ...
END # LAYER

MapFile after MapScript " $layer->set('labelitem', NULL); " and "
$layer->set('classitem', NULL); " : 

LAYER
 NAME "test"
 CLASSITEM ""
 LABELITEM ""
 ...
END # LAYER
