Phpsmtp sends an email

Php needs to send mail via smtp through a class smtp

The code for sending an email is as follows:

  1. Require_once 'smtp. php ';
  3. ######################################## ##
  4. $ Smtpserver = "smtp.sina.com"; // SMTP server
  5. $ Smtpserverport = 25; // SMTP server port
  6. $ Smtpusermail = "god_chen@sina.com"; // user email address of the SMTP server
  7. $ Smtpemailto = "45323333@qq.com"; // to whom to send
  8. $ Smtpuser = "name"; // User account of the SMTP server
  9. $ Smtppass = "123456"; // SMTP server user password
  10. $ Mailsubject = "Chinese"; // email subject
  11. $ Mailbody = "New Year's sensation in Chinese test"; // email content
  12. $ Mailtype = "HTML"; // The email format (HTML/TXT). TXT is a text email.
  13. ######################################## ##
  14. $ Smtp = new smtp ($ smtpserver, $ smtpserverport, true, $ smtpuser, $ smtppass); // Here, true indicates that authentication is used; otherwise, authentication is not used.
  15. $ Smtp-> debug = FALSE; // whether to display the sent debugging information
  16. $ Smtp-> sendmail ($ smtpemailto, $ smtpusermail, $ mailsubject, $ mailbody, $ mailtype)
