// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

// Starting May 30, 2022, Google will no longer support the use of third-party apps or devices 
// which ask you to sign in to your Google Account using only your username and password.

// Instead of authenticating with your GMail username/password, a GMail user can create an App Password
// and then login using their username/app_password.   It's literally the same, except it allows a GMail
// account owner to isolate passwords to specific applications.

// The Gmail account owner would first need to make sure she has 2-Step Verification setup for her account.
// Note: The 2FA verification is not a factor when authenticating with an app password. The 2FA is required
// to setup app passwords in the Google account console.  See Sign in with App Passwords

// After the GMail account owner has setup his app password, he simply uses the app password instead of his GMail account password.

// For example:
$imap = new CkImap();

$imap->put_Ssl(true);
$imap->put_Port(993);

$success = $imap->Connect('imap.gmail.com');
if ($success == false) {
    print $imap->lastErrorText() . "\n";
    exit;
}

$success = $imap->Login('user@gmail.com','srnyyvqajocnsvdp');
if ($success == false) {
    print $imap->lastErrorText() . "\n";
    exit;
}

print 'IMAP Success!' . "\n";

// For SMTP..

$mailman = new CkMailMan();

$mailman->put_SmtpHost('smtp.gmail.com');

$mailman->put_SmtpUsername('user@gmail.com');
$mailman->put_SmtpPassword('srnyyvqajocnsvdp');

$mailman->put_SmtpSsl(true);
$mailman->put_SmtpPort(465);

$success = $mailman->SmtpConnect();
if ($success == false) {
    print $mailman->lastErrorText() . "\n";
    exit;
}

$success = $mailman->SmtpAuthenticate();
if ($success == false) {
    print $mailman->lastErrorText() . "\n";
    exit;
}

print 'SMTP Success!' . "\n";
