problem with mapscript PointObj method Draw

[eric BELENFANT]

Hello,
I use php Mapscript 4.2 under linux 9.
I try adding a point on the map like this :

// DRAW MAP AND SET GEO EXTENT (IN MAP UNITS) IN SID FOR SUBSEQUENT ZOOM
ACTIONS //
$mapimg = $map->draw();


// ECRIT LES ETABLISSEMENTS AYANT DES FORMATIONS SUR LA CARTE
writeFormations($map,$mapimg,'%','400');//ne marche pas impossible d'écrire
le point avec le symbole
$couche=$map->getLayerByName("commune_symboles");
$monpoint = ms_newPointObj();
$monpoint->setXY(600000,220000);
$monpoint->draw($map,$couche,$mapimg,0,"");

I can't just see this point and the symbol i want to add with.
It gets on my nerves !!
If you could help me it would be nice !

Here is my .map file
