No "$objMap->insertLayer" in PHP Mapscript: OK. WORKAROUND NOT NEEDED!

[Michael H ärtel]

Hello Again!

Sorry for evoking some confusion with my mail. I
haven't noticed that there is a parameter for the map
object in the ms_newLayerObj function.

by the way the $obj_layer-><someproperty>=value thing
doesn't seem to work with PHP properly. (That's why
the second output didn't show the changed layer
properties I guess. The layer object was refered
correctly so my Assumption about the layer object
being outside the map object probably was incorrect).

I switched to 

$obj_layer->set(<some property> , value)

and this works fine now. I guess I don't need to use 
ms_newLayerObj(MapObj map [, layerObj layer]) in my
case.

Sorry about my mail,

Michael
