Spent ages trying to get this to work, then eventually remembered I had opened the mailbox READONLY - obviously you need write permission for setting flags!

示例 #1 imap_setflag_full() example
<?php
$mbox = imap_open("{imap.example.org:143}", "username", "password")
or die("can't connect: " . imap_last_error());
$status = imap_setflag_full($mbox, "2,5", "\\Seen \\Flagged");
echo gettype($status) . "\n";
echo $status . "\n";
imap_close($mbox);

My host allowed me to upgrade to IMAP and it is so much easier. I think the only way to accurately create any form of mail client with POP3 is to download the messages into an SQL database which is a big task to start with, considering the IMAP standards have the functionality we need built in.
I experimented with flag setting in POP3 and it seems they do not stick at all, and it is almost impossible to retrieve the number of unread messages (ie. the Seen / Unseen thing does not work)
Converted to IMAP and it's working - the majority of the functions in this section seem to be IMAP focussed and WILL NOT generally work with POP3
