Php needs to send mail via smtp through a class smtp The code for sending an email is as follows:
- Require_once 'smtp. php ';
- ######################################## ##
- $ Smtpserver = "smtp.sina.com"; // SMTP server
- $ Smtpserverport = 25; // SMTP server port
- $ Smtpusermail = "god_chen@sina.com"; // user email address of the SMTP server
- $ Smtpemailto = "45323333@qq.com"; // to whom to send
- $ Smtpuser = "name"; // User account of the SMTP server
- $ Smtppass = "123456"; // SMTP server user password
- $ Mailsubject = "Chinese"; // email subject
- $ Mailbody = "New Year's sensation in Chinese test"; // email content
- $ Mailtype = "HTML"; // The email format (HTML/TXT). TXT is a text email.
- ######################################## ##
- $ Smtp = new smtp ($ smtpserver, $ smtpserverport, true, $ smtpuser, $ smtppass); // Here, true indicates that authentication is used; otherwise, authentication is not used.
- $ Smtp-> debug = FALSE; // whether to display the sent debugging information
- $ Smtp-> sendmail ($ smtpemailto, $ smtpusermail, $ mailsubject, $ mailbody, $ mailtype)
