Hi Pierre,
Using PHP, it's quiet easy. You can simply create a new layer with only
your selection. I have'nt code in PHP (we work with perl-mapscript for
the moment).
I can add that it's easyer with a postgis database. You define a classic
layer to display all objects. And then you define a layer for selection
with a transparency. SQL expressions are very simple to produce.
regards,
Lionel
