Google Contacts API v3 Add/Update/Delete Contacts

I need a php 5.3 compatible script and three functions that use Google Contacts API ([login to view URL]) to add, update and delete entries in the google address book form php-mysql. Function 1: addressbook_add (id, first name, last name, phone, email, address, city, state, zip) will insert the entry in the google address book. (Give back the GoogleContactID?) Function 2 is addressbook_update. It will take the same arguments and will update the entry. Function 3 is addressbook_delete which will delete the entry given the id. The script runs in the background on the server. It does not need a frontend, only the functions with the library.
