How to make an email have an "Unread" flag, PHP: imap_open(), getMailPart()

Question

PHP

Hello!
I receive letters through the functions of the imap PHP extension.
As soon as the body of the letter is read to the end through the function: imap_fetchbody () - then on the server itself, this letter is displayed as read. And how to make it remain unread on the server?

Answer 1

en2.php.net/imap_fetchbody
FT_PEEK - Do not set the \Seen flag if not already set
imap_fetchbody ($imap_stream, $msg_number, $section, FT_PEEK);

Answer 2

Clears the value of the flag specified in the parameter:
imap_clearflag_full($mailBoxHandler, $mailNum, "\\Seen");
It helps me.
