[mapserver-users] php mapscript

[Sven Schroeter]

Alan,
thanks for the reply, I tried it with getFeature(), but there comes the same 
error.
nextShape() works only after msWhichShapes and here I need a rectobj.
But I want to use the script for queryByShape and queryByAttributes too.
Why there comes no array in $attr = $shpobj->values; ?
Any idea?
Sven
