creating shape for querying

[Ethan Alpert]

Although I don't use PHP...I regularly create shapes and call
queryByShape() using them as the query shape in perl.

I do know that the layer *being* queried can not be an inline layer and
must be a true data source.

hello Ethan

i get "[Tue Nov 29 15:27:49 2005] [error] [client 127.0.0.1] Premature
end of script headers: php.exe"

but when i use the shape $oGeo and add it into a dynamic layer, it is
well computed so i think it is in a good form enven if the bounds of the
shape are disabled (-1)

did you already query a layer by shape using such manually created
shape?


thanks
best regards
fx
