function getFeatureInfoByKeyFromSDF($key, $pathtoSDF){
$result=false;

if( file_exists($pathtoSDF)){

$mySDF = new COM("Autodesk.MgSdfToolkit.1");
//
$point = new COM("Autodesk.MgSdfDoublePoint.1");
$objExtent = new COM("Autodesk.MgSdfBoundingBox.1");
//
$mySDF->Open($pathtoSDF, 1, true);
//
$mySDF->BeginKeyIndexSearch ($key);
//
$object = $mySDF->SearchToNextObject();
$mySDF->EndSearch();
if($object){
$objExtent = $object->Extent;
$result=array("identifier" => "", "coordinates" => "");
$result["identifier"] = $object->key;
$result["coordinates"] = $objExtent->MinX . "," . $objExtent->MinY . " " . $objExtent->MaxX . "," . $objExtent->MaxY;
}else{
return $result;

$mySDF->Close();
}else{
$result=array("identifier" => "", "coordinates" => "");

return $result;

$xx = getFeatureInfoByKeyFromSDF('MC 9-866','C:\\Inetpub\\mapguide\\projects\\Wblite\\SDF\\WBMC09_FM.sdf');
if($xx){
echo "

The original post refers to MapGuide Enterprise or Open Source (inferred
from the AJAX viewer mention) so using the SDF COM Toolkit will not work
with the newer SDF+ version files.

This group really needs to be split up into MapGuide 6.5 and older and the
newer MapGuide to avoid these kind of ambiguities in posts and responses.

Our firm don't use MapGuide 6.5 no more.
we make new projects with MapGuide Open Source.

So how to get this coordinates from sdf file in PHP (ajax viewer)

I need to take x,y of middle of polygon - to make zoom to this.

I thing i is posilble take this coordinates with php.

Do you know kow?

Take a look at the findparcels.php file that comes with the PHP sample
application. This illustrates exactly what you are asking for. It uses the
FDO GetCentroid method to get the X and Y of the polygon centroid.
