[MapServer-users] PHP Mapscript: how to clone layers

[Jan Hartmann]

Yes, that's it. Thanks, Seth!

It was an insidious migration problem. The old way of cloning a layer 
($l2 = new layerObj($oMap,$l1);) still works, but ignores the second 
parameter. So you get a default new layer, with STATUS OFF. I filled 
every member but that. No wonder the layers didn't turn on. Could this 
function be made to fail when called with two parameters?
