I need to make a querybypoint on a layers that are wms layers.
the mapfile for the wms is

With mapscript the map appear no problem. But then i want to know if
i've got a layer that is on the point (0,48.20)
so here is my php file
<?php
$map_path="/var/www/html/testmapscript/mapfile/";
$map = ms_newMapObj($map_path."toto3.map") or die("on a mal charge le
.map");
echo "Nombre de couches".($map->numlayers)."<HR>";
$mpoint = ms_newPointObj();
$mpoint->SetXY(0,48.20);
// find into layer the most closed point
//------- LOOP ON LAYERS and get identify results.
$tot = $map->numlayers;
for ($i =0; $i < $tot; $i++) {
//------- get map layer.
echo "on teste $i ";
$oLayer = $map->getLayer($i);
//------- Verify Layer type
//------- Validate if query succeeds.
$check_query = $oLayer->queryByPoint($mpoint, MS_SINGLE,0);
echo "---$check_query----".($oLayer->getNumResults())." ";
if ($check_query != MS_SUCCESS) {echo "Rien ".$oLayer->name."<BR> ";}
else {echo "on trouve une intersection avec
".$oLayer->name."<BR>";}
//------- Open layer for data input.
$oLayer->open();
} // for i
?>
He find that my layer world_borders (from the shapefile) in on the point
but not the second one. But both should be find.
Please why can't i querybypoint on a wms layer ?
