Problem with PHP MapScript Wrappers for WxS Services

Hi all-
I am trying to get the MapScript Wrappers for WxS Services working
with PHP. I am running mapserver 4.10.0 on a linux server with PHP
4.3.9 (this is not built from source, it is the default redhat build,
not sure if this matters). I am tryin gto start by implementing the
examples at http://mapserver.gis.umn.edu/docs/howto/wxs_mapscript
However, I can't even get the fisrt example (the get capabilites
example) to function properly. I have been able to track down when it
fails. It seems to load the mapscript libray okay and create the
request object ($request = ms_newowsrequestobj();). However, it seems
that the requst object comes back empty despite parameters being
supplied with the URL. The URL I am using, the php code, and the
output are below. Any thoughts on what might be wrong here would be
greatly appreciated. In my php script everything starting at and after
the line $request->loadparams(); is commented out, becuase it fails
when I try to use loadparams(), I am guessing because numparams in
$request is 0.
By the way at present this server is not avaialable to the public
until it gets cleared by our IT guys as being secure. However, I'd be
happy to provide more info if it might help solve problem. Hopefully
we'll be open to the public soon.
