calculating extents with mapscript

[Gail Long]

Hi all,

I'm working in phpmapscript and doing a very simple web app that will allow 
searches by attribute to return a feature from a shape file (.shp).  I have 
it so that when querybyattribute is run it returns an exact match for the 
attribute string entered in a form and then zooms to the appropriate 
location.

I'm getting the correct extents for the feature by using:

$extents = $shape->bounds;

and getting the rectObj.

What I need to know is how to get the bounds or rectangle if there is more 
than one attribute returned in the results set because the user entered a 
substring or partial match rather than an exact match.  I need to handle 
both cases.

Any examples would be great!

Thanks in advance.
