[Mapserver-users] Questions about PHP/MapScript

[Gheysen Thibaut]

Thanks for your response but I want to create a shapefile dynamically : I
want to create a new shapefile with only a few shapes of the layer. But I
don't know how to retrieve this shapes from the current map for add in a new
shapefile.
