Dylan, Here is some sample code from one of our apps here at PSU. I hope
it is useful. Sorry everyone for the re-post, but I did the bonehead
error of not changing the subject line, so if anyone was following
Dylan's thread they would not know that this was posted...

Subject: phpmapscript: changing a layer's style
Greetings,
is there a simple way to change an existing layer's style?
so far i am able to change a layer's filter expression, etc. but not able to
adjust the style defined in the first class.
any examples out there?
thanks in advance!
