problem with PHP/MapScript

[ari sutanto]

Hi list, 
I have any problems about GMap75 PHP/MapScript.
i have an aplication of php, like this,
<?php
dl("php_mapscript.dll");

define("MAPFILE","../maps/routing.map");

$start=0;
$end=0;
$cx1=0;
$cy1=0;
$cx2=0;
$cy2=0;

if($HTTP_GET_VARS["start"])
  $start=$HTTP_GET_VARS["start"];

if($HTTP_GET_VARS["end"])
  $end=$HTTP_GET_VARS["end"];

if($HTTP_GET_VARS["cx1"])
  $cx1=$HTTP_GET_VARS["cx1"];

if($HTTP_GET_VARS["cx2"])
  $cx2=$HTTP_GET_VARS["cx2"];

if($HTTP_GET_VARS["cy1"])
  $cy1=$HTTP_GET_VARS["cy1"];

if($HTTP_GET_VARS["cy2"])
  $cy2=$HTTP_GET_VARS["cy2"];


$delta=0.01;

$map_file=MAPFILE;
$map=ms_newMapObj($map_file);

$l=$map->getLayerByName("network");
if($l) {
  if($l && $start!=0 && $end!=0) {

    if($cx1!=0 && $cy1!=0 && $cx2!=0 && $cy2!=0 && 
       $cx1!=$cx2 && $cy1!=$cy2) {
      $minx = min($cx1,$cx2)-$delta;
      $miny = min($cy1,$cy2)-$delta;
      $maxx = max($cx1,$cx2)+$delta;
      $maxy = max($cy1,$cy2)+$delta;

      $map->setextent($minx,$miny,$maxx,$maxy);

      $rectobj = $map->extent;
      $ll_x = $rectobj->minx;
      $ll_y = $rectobj->miny;
      $ur_x = $rectobj->maxx;
      $ur_y = $rectobj->maxy;
		  
      $sql="the_geom from (select gid, the_geom from
"."shortest_path_astar2_as_geometry_internal_id_directed('tercepat',
".$start.", ".$end.", ".$ll_x.", ".$ll_y.", ".$ur_x.",
".$ur_y.", false, true)) as g using unique gid using
SRID=-1";

      $l->set('data', $sql);
      $l->set('status', MS_ON);
					  
    }
  }
  else {
    $l->set('status', MS_OFF);
  }
}
$image=$map->draw();
$image_url=$image->saveWebImage();

?>

i put into Gmap template in gmap75.phtml, why the
result of this doesn't come up in map display? but
actually the case appear in tmp folder.
Thanks,

Regards,

Ari Sutanto
