[Mapserver-users] Unique? Was: mapscript - queryByPoint help, simple Q

[poff]

Hello

I know everyone is busy - and thanks a lot for your help.

Only, does _no-one_ use querbypoint with php mapscript?

It's a great feature if I could get it working, and definitely something to 
go in Wiki someday!

Thanks

P
