So, with our individual username and password settings set, we connect to Gmail account. Once the account is connected, we request all or unseen emails. If any emails are found, then we can reverse sort the emails so that the newest emails appear on the top.

Now if you attach the above email to an email with the message text in plain text and HTML, imap_fetchbody() will use this type of part number system:

(empty) – Entire message
0 – Message header
1 – MULTIPART/ALTERNATIVE
1.1 – TEXT/PLAIN
1.2 – TEXT/HTML
2 – MESSAGE/RFC822 (entire attached message)
2.0 – Attached message header
2.1 – TEXT/PLAIN
2.2 – TEXT/HTML
2.3 – file.ext
