I've previously posted sample PHP code that demonstrates this; it should
be in the list archives. (When I have an hour or two free I'll clean up
that code and add it to the PHP samples in the Wiki.)

The basic process is to load the XML layer definition, modify it, and then
save the modified version to the session repository. Then you'll have to
follow a similar process to modify your map definition to point to the
modified layer definition (that is now in the Session repository rather
than in the Library repository), and then modify your layout definition to
point to the new map definition.
