[maplab-users] Search objects in a map

[Jeff McKenna]

Hello,

I think you're having a hard time getting help on this list because you 
are asking about very detailed functionality with 
phpmapscript/mapserver.  You will find more help on the main mapserver 
list (http://lists.umn.edu/archives/mapserver-users.html) where the 
developers of mapserver and phpmapscript could probably help you.
Sorry.
