$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = 'your-email@example.com';
$mail->Password = 'your-password';

$mail->isHTML(true);
$mail->Subject = 'Hello World';
$mail->Body = '<h1>Hello, PHPMailer!</h1>';

if ($mail->send()) {
    echo '邮件发送成功!';
} else {
    echo '邮件发送失败:' . $mail->ErrorInfo;
}

In this example, we first instantiate a PHPMailer object, and set the sender address and name through the setFrom method, and set the recipient through the addAddress method. Sender's address and name. Then, specify the email content as HTML format through the isHTML method, and use the Subject and Body attributes to set the subject and content of the email.
