PHPMailer 封装，让发邮件更简单

mail 函数使用方法：

\mail::to('tom@example.com')
        ->subject('test subject')
        ->body('<p>hi world</p>')
        ->embed(['img/ban.png', 'img/about.png'])
        ->attach('img/test.pdf')
        ->send();

如果没有 phpdotenv, 需要把相应的 env()改下。

推荐封装一个 css_inline 函数。

如果没有 Facade ，使用方法：


$mailer = new \Classes\Mail;


$mailer->to('tom@example.com')
        ->subject('test subject')
        ->body('<p>hi world</p>')
        ->embed(['img/ban.png', 'img/about.png'])
        ->attach('img/test.pdf')
        ->send();
