Gmail - 使用imap存档电子邮件

How can I archive an email in gmail with imap using php?

I can move an email to another folder with:

imap_mail_move($inbox, $email_number, "AnotherFolder");

But, I'm trying:

imap_mail_move($inbox, $email_number, "Archive");

And the email does not move. I also tried "[Gmail]\Archive".
