Thanks Eric,
But i like to display the query resutls in the same page. I
written like this
$mappointq = ms_newpointObj();
$mappointq->setXY($map_x,$map_y);
$mappointq->setXY($map->width / 2,$map->height / 2);
for ($ilayer=0; $ilayer<=$map->numlayers; $ilayer++)
{
$selLayer = $map->GetLayer($ilayer);
$queryResult = $selLayer->queryByPoint($mappointq, MS_MULTIPLE, -1);
}
for the above code i did not get any results. So how can i get the results
form the layer? Can anyone help this point.

You will need to define a TEMPLATE "template.html" in your LAYERS. Even
if you do not want to use the templates.html to display the results, you
still need to have a TEMPLATE in the layer. The html does not even to
exist.
Hope this helps.
