displace on a map..

[sophie chaveroux]

First of all i'd like to thanks Jean-Guilhem thanks to who i succeed in
resolving my preview problem ...Merci!

Now i want to create an internet site and i would like that the customer
choose a  department and that mapserver display this department...My
problem is that i don't know how to say mapserver to move automaticaly
on the place the custumer has choice....that's suppose dynamical
extents...I suppose it should be done with php-mapscript but i'm
beginner in programmation so every advice would be welcome,in fact i
don't know how to start.... Thanks...
