Hello,
I used your slightly changed PHP and the mapfile below, it worked 
perfectly for me. Maybe your problems were caused by the extent defined 
in your mapfile?
Regards
Ludwig

<?php
$map = ms_newMapObj('e:\website\WVER_IMS\mapfiles\test.map');
$daLayer = ms_newLayerObj($map);
$daLayer->set("type", MS_LAYER_POINT);
$daLayer->set("status", MS_ON);
$class = ms_newClassObj($daLayer);
$style = ms_newStyleObj($class);
$style->color->setRGB(255,0,0);
$style->set("symbolname", "circle");
$style->set("size", 10);
$my_point = ms_newpointObj();
$my_point->setXY(60,60);
$image=$map->draw();
$my_point->draw( $map, $daLayer, $image, 0, "Temp Point" );
$image_url=$image->saveWebImage();
echo "<img src='$image_url'/>";
?>

map
   name "test"
   units dd
   extent 0 0 100 100
   size 640 480
   imagecolor 255 255 255

       IMAGEPATH "your_path"
       IMAGEURL "your_url"
   END
   SYMBOL

       POINTS

           1 1
           1 0
           0 0
       END
   END
end
