Building an IMAP Email Client with PHP (Publication)
https://www.toptal.com/php/building-an-imap-email-client-with-php
Developers sometimes run into tasks that require access to email mailboxes. In most cases, this is done using the Internet Message Access Protocol, or IMAP. As a PHP developer, I first turned to PHP's built in IMAP library, but this library is buggy and impossible to debug or modify. So today we will create a working IMAP email client from the ground up using PHP. We will also see how to use Gmail's special commands.
