[Editor's Note:

Serializing the object, storing it and then (on the next page) unserializing it WILL work.

End Note]



the big problem for PHP is it can't save in session an COM object



an samples code is here. This works just first time, then give the error:

Call to undefined method com::Refresh() on line  $mMap->Refresh();

the reson is he can't save the object $mMap in session



<?php

    session_start();

      if (isset($_SESSION['map'])) {

            $mMap = $_SESSION['map'];

        }

        else

        {

        $ArcIMSConnector = new COM ("aims.ArcIMSConnector")  or die("can not create AIMS message object");

            echo "Loaded ArcIMSConnector, <br>";

            $ArcIMSConnector->ServerName = "map.sdsu.edu";

            $ArcIMSConnector->ServerPort = 5300;



            $mMap = new COM ("aims.Map")  or die("can not create aims.Map message object");

            echo "Loaded aims.Map, <br>";

            print "AIMS-ServerName= $ArcIMSConnector->ServerName <br>";



            $resultInit= $mMap->InitMap($ArcIMSConnector,"Worldgeography");



            $mMap->Width    = 400;            //                                'Width of the map in pixels

            $mMap->Height   = 300;            //                                'Height of the map in pixels

            $mMap->BackColor = 15130848;

            $_SESSION['map'] = $mMap;

        }



    $resultRefresh = $mMap->Refresh();                                //Refresh the map

    $urlImage      = $mMap->GetImageAsUrl();

    print "<br>urlImage=$urlImage<br>";



    print "<br><IMG SRC='$urlImage'>";



/*

    $ArcIMSConnector->Release();

    $ArcIMSConnector = null;



    $mMap->Release();

    $mMap = null;

*/
