php通过smtp发送邮件需要通过一个类smtp

发邮件的代码如下：

  1. require_once 'smtp.php';
  3. ##########################################
  4. $smtpserver = "smtp.sina.com";//SMTP服务器
  5. $smtpserverport = 25;//SMTP服务器端口
  6. $smtpusermail = "god_chen@sina.com";//SMTP服务器的用户邮箱
  7. $smtpemailto = "45323333@qq.com";//发送给谁
  8. $smtpuser = "name";//SMTP服务器的用户帐号
  9. $smtppass = "123456";//SMTP服务器的用户密码
  10. $mailsubject = "中文";//邮件主题
  11. $mailbody = "

    中文

    测试下能淤泥新年感";//邮件内容
  12. $mailtype = "HTML";//邮件格式（HTML/TXT）,TXT为文本邮件
  13. ##########################################
  14. $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证.
  15. $smtp->debug = FALSE;//是否显示发送的调试信息
  16. $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)
