前几天用CI写项目用到了一个发送邮件函数，今天把它贡献出来，希望有用，什么都不说了，直接上方法

public function sendMail() {  $config['protocol']  = 'smtp';//采用smtp方式  $config['smtp_host'] = 'smtp.126.com';  $config['smtp_user'] = 'mytest@126.com';//你的邮箱帐号  $config['smtp_pass'] = 'mytest123';//你的邮箱密码  //$config['smtp_pass'] = 25;  $config['charset']   = 'utf-8';  $config['wordwrap']  = TRUE;  $config['mailtype']  = "html";  $this->load->library('email');//加载email类  $this->email->initialize($config);//参数配置  $this->email->from('lijunhua19862008@126.com', '我是发件人 陈文');  $this->email->to('my@test.com');  //$this->email->cc('another@another-example.com');  //$this->email->bcc('them@their-example.com');  $this->email->subject('Email Test to guijia');  $this->email->message('Testing the email class.');  $this->email->attach('static/upfile/'.$sfile.'');  //显示发送邮件的结果，加载到res_view.php视图文件中  if(!$this->email->send()){  $data="邮件发送失败，可能是由您的发件人或者密码填写不匹配造成";  } else {  $data="邮件发送成功";  }  echo $data;  echo $this->email->print_debugger();}
