本文实例讲述了Yii2使用swiftmailer发送邮件的方法。分享给大家供大家参考，具体如下：

'mail' => [

    'class' => 'yii\swiftmailer\Mailer',

    'viewPath' => '@backend/mail',

    'useFileTransport' => false,//set this property to false to send mails to real email addresses

    //comment the following array to send mail using php's mail function

    'transport' => [

      'class' => 'Swift_SmtpTransport',

      'host' => 'smtp.gmail.com',

      'username' => 'username@gmail.com',

      'password' => 'password',

      'port' => '587',

      'encryption' => 'tls',

     ],

  ],

],

控制器：

Yii::$app->mail->compose('your_view', ['params' => $params])

 ->setFrom([\Yii::$app->params['supportEmail'] => 'Test Mail'])

 ->setTo('to_email@xx.com')

 ->setSubject('This is a test mail ' )

 ->send();

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
