PHP 使用 SMTP 发送邮件（PEAR）

PHPer 多数使用 mail 函数来发送邮件，但我们可以使用其他的 SMTP 服务器来发送，这里推荐使用 PEAR’s mail package 来发送邮件。

1. $subject = "This mail is sent from SMTP.";
2. $mail_body = "This is the body of the mail which is sent using SMTP.";
3. $from = "From: From Name ";
4. $to = "To: To Name ";
5. $receiver = "[e-mail]";
7. // Setting up the headers
8. $headers["From"] = $from;
9. $headers["To"] = $to;
10. $headers["Subject"] = $subject;
11. $headers["Reply-To"] = "[e-mail]";
12. $headers["Content-Type"] = "text/plain; charset=ISO-2022-JP";
13. $headers["Return-path"] = "[e-mail]";
15. // Setting up the SMTP setting
16. $smtp_info["host"] = "smtp.server.com";
17. $smtp_info["port"] = "25";
18. $smtp_info["auth"] = true;
19. $smtp_info["username"] = "smtp_user";
20. $smtp_info["password"] = "smtp_password";
22. // Creating the PEAR mail object :
23. $mail_obj =& Mail::factory("smtp", $smtp_info);
25. // Sending the mail now
26. $mail_sent = $mail_obj->send($receiver, $headers, $mail_body);
28. // If any error the see for that here:
29. if (PEAR::isError($mail_sent)) { print($mail_sent->getMessage());}
