//1.设置邮件的Content-Type,要不然网站的消息内容里面的html标签会被当做纯文本处理
$smtpHeaderContentType = new SmtpHeaderContentType();
$smtpHeaderContentType->setType('text/html');
//2.设置编码集并添加Content-Type
$headers = new SmtpHeaders();
$headers->setEncoding('utf-8');
$headers->addHeader($smtpHeaderContentType);
//第二步：设置消息的相关
$message = new SmtpMessage();
$message->setHeaders($headers);
$message->addTo($this->mailTo)->addFrom($this->mailFrom)->setSubject($this->subject)->setBody($this->body);
//邮件的内容
//第三步：设置Smtp的相关链接参数
$smtpOptions = new SmtpOptions();
$smtpOptions->setHost($this->host)->setPort($this->port)->setConnectionClass('login')->setConnectionConfig(array('username' => $this->username, 'password' => $this->password, 'ssl' => 'ssl'));
//第四步：加载配置，发送消息
$smtpTransport = new SmtpTransport();
$smtpTransport->setOptions($smtpOptions);
//加载配置
$smtpTransport->send($message);
//发送消息
