mapscript removestyle() help

[krishna S]

Hello all, i was trying to remove the styles object from the styles array
using php mapscript and i couldnt get the syntax for it.

i dont know if these lines need some thing else

         $layername = $map->getLayerByName("somelayer");
         $class = $layername->getClass(0);
         $style = ms_newStyleObj($class);
         $temp = $class.removeStyle(0);

Could anyone suggest me with this ....
