Thanks Mr.Eric. I applied as u said. still i am not getting.

i defined in this way my MAP file layer

 LAYER//Layer Def. start
    NAME "Boundary"
    STATUS ON
    CONNECTIONTYPE OGR
    CONNECTION "data/Boundary.tab"
    TYPE POLYGON
    CLASSITEM "NAME"
    LABELITEM "NAME"
    TEMPLATE "Malaya.html"  //I defined here the template

    METADATA
      "DESCRIPTION"   "Daerah"
      "RESULT_FIELDS" "Name"
      "WMS_TITLE"    "Selected Information"
      "WMS_ABSTRACT"    "more information."
      "WMS_SRS"    "EPSG:26915"
    END
    CLASS

     COLOR 255 255 200
     OUTLINECOLOR 0 0 0
     LABEL
          MINFEATURESIZE 40
          MINDISTANCE 150
          POSITION CC
          SIZE TINY
          COLOR  0 0 200
    END

    END
End//Layer Def. end

for the above layer i written this code for geting the result
if ( isset($map_x) && isset($map_y) && strcmp($zoomdir, "QUERY_POINT") ==
0 )
{
 echo "your at the query entery point just enter<br>";

 for ($ilayer=0; $ilayer<=$map->numlayers; $ilayer++)
 {
   $selLayer = $map->GetLayer($ilayer);
  // Pointing the map point to where the user clicked
   $mappointq = ms_newpointObj();
  $mappointq->setXY($map_x,$map_y);
   echo $map_x. "<br>" . $map_y;
   //$selLayer->{template} = "bogus.html";

   $mappointq->setXY($map->width / 2,$map->height / 2);

   $queryResult = $selLayer->queryByPoint($mappointq, MS_MULTIPLE, -1);
   // here i am geting this error message " PHP Warning:  MapServer Error in
msQueryByPoint(): No matching record(s) found"
 echo $queryResult;
}
}
