Hello,
 
How do I get my php/mapscript (4.0)application that uses a MapInfo layer (OGR)  to "zoom&center itself" on the results of my queryByAttributes query.
 
assuming I have this:
$searchitem = "Ontario";
 
$SearchLayer = $MapOBJ->getLayerByName( "Canada" );
$SearchLayer ->queryByAttributes('Province_Name','/'.$searchitem .'/',MS_MULTIPLE);
 
if ($SearchLayer ->getNumResults() > 0 )
{
     //how do I zoom into the found results if they are polygons?
     //how do I zoom into the found results if they are points?
 
    //how do I highlight the found results?
}
 
Thanks,
Denis
