twitter profile edit using php curl

im trying to edit my twitter bio and photo using php/curl. its a multipart form upload that I cant seem to get to work. i can login and navigate to the /settings/profile page using curl but when i attempt to post the array of form data it does not work. what i need is the code that will allow me to edit twitter bio and photo. it will be some curl_opts, an array of postfields and whatever else thats required to get this to work i don't need the code to login to twitter and navigate to the /settings/profile page this should be just a little bit of code and really easy for someone
