creating shape for querying

[Fx Gamoy]

Hello everybody,

i would like to create a shape in order to querybyshape a layer.
I ve got two arrays xgeo and ygeo

<?

$oGeo =  ms_newShapeObj(MS_SHAPE_POLYGON);
$part = ms_newLineObj();
for($v=0;$v<count($xgeo);$v++)
  $part->addXY($xgeo[$i],$ygeo[$i]);

$oGeo->add($part);
$rep=@$oLayer->queryByRect($oGeo);
?>
the bounds of this shape are (-1,-1,-1,-1) but i can add it in a dynamic layer
and see it on the computed image.
but
when i use this shape into querybyshape, php fail

I ve read some posts dealing with this? the php_mapscript 4.6 don't provide the
$Shape->setbounds() function for setting the bounds of the shape.

is there un artefact to compute a querybyshape using a self created shape??

Thanks.....
have a nice day
fx
