This article introduces how to use php-imap to query and operate email inboxes. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

Recently, in business scenarios, I have received and parsed emails actively sent by users, and used php-imap to achieve this Requirements, record them.

Determine the implementation method

There are two protocols for reading emails: POP3 and IMAP, the difference is: The POP3 protocol allows email clients to download emails on the server, but operations on the client will not be fed back to the server. IMAP Provides two-way communication between webmail and email clients. Operations on the client will be fed back to the server. For operations on emails, the emails on the server will also take corresponding actions.

The requirement requires that after processing the user's email, the email should be marked as processed, so the IMAP protocol is selected.

Installation dependencies

Both local and server php need to install the imap extension. Add the php-imap (https://github.com/barbushin/php-imap) extension to the project's composer.json as follows:

"require": {
  "php-imap/php-imap": "^3.1",
