use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'phpmailer/autoload.php';

$mail = new PHPMailer(true);
try {
    //Server settings
	$mail->SMTPDebug  = 2;
	$mail->isSMTP();
	$mail->Host       = 'ssl://smtp.gmail.com';
	$mail->SMTPAuth   = true;
	$mail->Username   = 'xxxxx@gmail.com';
	$mail->Password   = 'xxxxx';
	$mail->SMTPSecure = 'tls';
	$mail->Port       = 465;

    //Recipients
    $mail->setFrom('xxxxx@gmail.com', 'Mailer');
    $mail->addAddress('yyyyy@gmail.com');     // Add a recipient

    //Content
    $mail->isHTML(true);
    $mail->Subject = 'Test';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
