(PHP ActiveX) 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.

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Imap')
$imap = new COM("Chilkat.Imap");

// Use TLS
$imap->Ssl = 1;
$imap->Port = 993;
$success = $imap->Connect('MY-IMAP-DOMAIN');
if ($success != 1) {
    print $imap->LastErrorText . "\n";
    exit;
}

// Authenticate
$success = $imap->Login('MY-IMAP-LOGIN','MY-IMAP-PASSWORD');
if ($success != 1) {
    print $imap->LastErrorText . "\n";
    exit;
}

// Get the list of capabilities:
$caps = $imap->capability();
print '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) == 1) {
    print 'IMAP server supports the QUOTA extension.' . "\n";
}

if ($imap->HasCapability('IDLE',$caps) == 1) {
    print 'IMAP server supports IDLE.' . "\n";
}

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