If you're just interested in reading the emails in a Gmail inbox you should forgo the cURL pseudo-browser path; instead, enable POP or IMAP on the Gmail account and use PHP's excellent IMAP/POP3 functions to access the Gmail inbox.

If on the other hand you're trying to create some sort of single-sign-on service you're straight out of luck. Why is this? Well, even if your server manages to authenticate and persist cookies from Gmail, you have no way of storing these Gmail cookies in the client's browser. Only requests that originate from mail.google.com can set Gmail cookies. This is known as Same origin policy.
