[Mapserver-users] getLayerByName phpMapscript

[Inna Janssen]

Just get all Layers by index and compare if it has the name of the layer you want to add:

$found=false
for($i=0;$i<$map->numlayers;$i++) {
 $layer = $map->getLayer($i);
 if  ($layer->name == $YourSearchedLayerName) { $found=true;break}
}
if (!$found) add the layer
else don't add it
