php_mapscript - showing polygon and point/annotation layers

[Mike Reilly]

Robert:

Thanks for your prompt reply. I'd tried something similar:

/* for($a=0;$a<count($layers);$a++){
echo $layers[$a];
$currentlayer=$mymap->getLayerByName($layers[$a]);
$currentlayer->status=MS_OFF;
echo $currentlayer->status."<br>";
echo
}
*/ 

but for some reason I still got all the layers displayed. I'll give it 
another run and double check tho!
