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
