[phpMapscript]display the layer but not the label

[Julien Bessiere]

Hi,
I'm building and displaying a layer from php mapscript.
That's work fine except the label that doesn't show up. No error message.
Here is my code, any idea of what i've done wrong?

***************************************************
**** NEW LAYER ************************************
$ilayer = ms_newLayerObj($map);
$ilayer->set("name",$layer_name);
$ilayer->set("type",MS_POINT);
$ilayer->set("status",MS_ON);
$labelitem =
"test";					$ilayer->set("labelitem",$labelitem);						$ilayer->setprojection($projType);

****************************************************
***** NEW CLASS ************************************
$classpoint = ms_newClassObj($ilayer);

***** NEW LABEL ************************************
$label = $classpoint->label;
$label->set("position", MS_CC);
$label->set("font","sans");
$label->set("type",MS_TRUEYPE);
$label->set("size",MS_MEDIUM);
$label->color->setRGB(22,8,3);
$label->backgroundcolor->setRGB(0,0,0);
$label->set(minsize,4);
$label->set(maxsize,100000);

***** NEW STYLE *************************************
$stylepoint = ms_newStyleObj($classpoint);
$stylepoint->set("symbolname","rond");
$stylepoint->set("size",10);
$stylepoint->color->setRGB($R,$G,$B);

***** LOOP DRAWING THE POINTS ************************
foreach ($row[4] as $coord){
	$poi[$i] = ms_newPointObj();
	$long = $coord[0];
	$lat = $coord[1];
	$poi[$i]->setXY($long,$lat);
	$poi[$i]->draw($map, $ilayer, $image, 0, "id");
}

Thx for your help.
