view outgoing post string?

hi,
i would like to be able to see the outgoing post variables from my php curl
script, is there any simple way to do this? the reason i ask is that there
appears to be a discrpancy between the post variables i pass to curl with

curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,$post);

and the post variables exiting curl as https.

i've tried to observe the output myself by running everything though a proxy
(webscarab), like so:
curl_setopt($ch,CURLOPT_HTTPPROXYTUNNEL,0);
curl_setopt($ch,CURLOPT_PROXY,"http://127.0.0.1:8008"); //webscarab operats
on localhost (127.0.0.1), port 8008 by default

this would work fine, except that im using https and i can't figure out how
to get the certificate into the correct format (but that's beside the point
of this message).

so yeah the easiest thing would be if i could just view the outgoing post
string. unfortunately neither     curl_setopt($ch,CURLOPT_VERBOSE,1);
or     curl_setopt($ch,CURLOPT_HEADER,1);    show me the post string.

any help would be much appreciated!
