PHP ActiveX Requires Chilkat v11.0.0+

Mark IMAP Email as Read/Unread (Seen/Unseen)

Demonstrates how to mark emails as read or unread. PHP ActiveX

<?php

$success = 0;

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

$imap = new COM("Chilkat.Imap");

//  Connect to an IMAP server.
//  Use TLS
$imap->Ssl = 1;
$imap->Port = 993;
$success = $imap->Connect('imap.example.com');
if ($success == 0) {
    print $imap->LastErrorText . "\n";
    exit;
}

//  Login
$success = $imap->Login('myLogin','myPassword');
if ($success == 0) {
    print $imap->LastErrorText . "\n";
    exit;
}

//  Select an IMAP mailbox
$success = $imap->SelectMailbox('Inbox');
if ($success == 0) {
    print $imap->LastErrorText . "\n";
    exit;
}

//  Set PeekMode so that downloaded messages are not
//  automatically marked as seen.
$imap->PeekMode = 1;

//  The NumMessages property contains the number of messages 
//  in the currently selected mailbox.
$numMsgs = $imap->NumMessages;
if ($numMsgs == 0) {
    exit;
}

$email = new COM("Chilkat.Email");

for ($i = 1; $i <= $numMsgs; $i++) {
    //  Download each email by sequence number (not UID)
    $success = $imap->FetchEmail(0,$i,0,$email);
    if ($success == 0) {
        print $imap->LastErrorText . "\n";
        exit;
    }

    //  If desired, mark the email as SEEN.  There are two
    //  ways to do it:

    //  1) Set the flag directly by using the sequence number
    //  Indicate that we are passing a sequence number and
    //  not a UID:
    $bIsUid = 0;
    //  Set the SEEN flag = 1 to mark the email as SEEN,
    //  or set it to 0 to mark it as not-seen.
    $success = $imap->SetFlag($i,$bIsUid,'SEEN',1);
    if ($success == 0) {
        print $imap->LastErrorText . "\n";
        exit;
    }

    //  2) Alternatively, we can use the email object.
    //  When an email is downloaded from the IMAP server
    //  Chilkat will add a "ckx-imap-uid" header to the email.
    //  This makes it possible to know the UID associated with
    //  the email.  (This is not the sequence number, which may change
    //  from session to session, but the UID which does not change.
    //  The SetMailFlag method is identical to SetFlag, except
    //  it gets the UID from the ckx-imap-uid header.
    //  For example:
    $success = $imap->SetMailFlag($email,'SEEN',1);
    if ($success == 0) {
        print $imap->LastErrorText . "\n";
        exit;
    }

}

//  Disconnect from the IMAP server.
$success = $imap->Disconnect();
