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';
  2. ##########################################
  3. $smtpserver = "smtp.sina.com";//SMTP服务器
  4. $smtpserverport = 25;//SMTP服务器端口
  5. $smtpusermail = "god_chen@sina.com";//SMTP服务器的用户邮箱
  6. $smtpemailto = "45323333@qq.com";//发送给谁
  7. $smtpuser = "name";//SMTP服务器的用户帐号
  8. $smtppass = "123456";//SMTP服务器的用户密码
  9. $mailsubject = "中文";//邮件主题
  10. $mailbody = "

    中文

    测试下能淤泥新年感";//邮件内容
  11. $mailtype = "HTML";//邮件格式(HTML/TXT),TXT为文本邮件
  12. ##########################################
  13. $smtp = new smtp($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.
  14. $smtp->debug = FALSE;//是否显示发送的调试信息
  15. $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)
