IMAP Capability

Demonstrates how to send the CAPABILITY command to request a listing of capabilities that the IMAP server supports. A capability name which begins with "AUTH=" indicates that the server supports that particular authentication mechanism. Chilkat2 PHP

<?php

use Chilkat2\Imap;

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

$imap = new Imap();

// Use TLS
$imap->Ssl = true;
$imap->Port = 993;
try {
    $imap->Connect('MY-IMAP-DOMAIN');

    // Authenticate
    $imap->Login('MY-IMAP-LOGIN', 'MY-IMAP-PASSWORD');
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// Get the list of capabilities:
$caps = $imap->Capability();
echo 'Capabilities: ', $caps, "\n";

// Here is an example of the string returned:
// * CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN X-GM-EXT-1
// UIDPLUS COMPRESS=DEFLATE ENABLE MOVE CONDSTORE ESEARCH UTF8=ACCEPT APPENDLIMIT=35882577
// LIST-EXTENDED LIST-STATUS

// Chilkat v9.5.0.58 introduces the HasCapability method to
// check to see if a particular capability exists:
if ($imap->HasCapability('QUOTA', $caps)) {
    echo "IMAP server supports the QUOTA extension.\n";
}

if ($imap->HasCapability('IDLE', $caps)) {
    echo "IMAP server supports IDLE.\n";
}

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