Determine the Number of Unseen Email Messages

Demonstrates how to determine how many unseen messages exist in an email account on an IMAP server. PHP Extension

<?php

include("chilkat.php");

$success = false;

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

$imap = new CkImap();

// Connect to an IMAP server.
// Use TLS
$imap->put_Ssl(true);
$imap->put_Port(993);
$success = $imap->Connect('imap.example.com');
if ($success == false) {
    print $imap->lastErrorText() . "\n";
    exit;
}

// Login
$success = $imap->Login('***','***');
if ($success == false) {
    print $imap->lastErrorText() . "\n";
    exit;
}

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

// After selecting the mailbox. the total number of emails
// is immediately available:
$totalNum = $imap->get_NumMessages();
print 'Num messages = ' . $totalNum . "\n";

// To determine the number of unseen messages, a call
// to Search is required, which returns the set of UIDs
// of all unseen messages.

// We can choose to fetch UIDs or sequence numbers.
$fetchUids = true;
$messageSet = new CkMessageSet();
$success = $imap->QueryMbx('UNSEEN',$fetchUids,$messageSet);
if ($success == false) {
    print $imap->lastErrorText() . "\n";
    exit;
}

$numUnseen = $messageSet->get_Count();
print $numUnseen . "\n";

print 'UIDs ----' . "\n";

// Display the UIDs
$i = 0;
while ($i < $messageSet->get_Count()) {
    print $messageSet->GetId($i) . "\n";
    $i = $i + 1;
}

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