Hi Nelson,
You can use the GROUP attribute for each layer, setting it to the same
value (ex : GROUP "COMPOSITE")
they'll not be linked, but you'll be able to retrieve thse layers using
the group name :
$aLayers = $pMap->getLayersIndexByGroup("COMPOSITE")
and then loop on the $aLayers array to switch then on/off

Hi,
I would like to link two layers of different geometry types. 1 layer
contains points, the other layer contains lines. The points and lines
are shown together to display a composite object on a map. If the user
no longer wants to see that composite object on the map then I would
like to turn off both of the layers. I am sure I can do it
programmatically, but I would like to know if they can be linked in the
MapFile?
Thanks,
Nelson
