[mapserver-users] mapextent of a selected polygon

[Lionel]

Hi,

I know it's possible to obtain a layer global mapextent. But do you know if 
it's possible to obtain the mapextent of a selected polygon in a layer. I 
work with phpmapscript and I would like to zoom at an entire polygon (or 
group of polygons) when it's selected by a user.
Another solution is to store each mapextent of each polygon obtained with 
another software (like arcinfo or grass) in a separate file, but I'd like to 
avoid this and to keep a dynamic method.
Thanks in advance,
Lionel
