当你还在纠结php内置的mail()函数不能发送邮件时，那么你现在很幸运，此时的这篇文章可以帮助到你！

php利用smtp类来发邮件真是屡试不爽，我用过很久了，基本上没出过问题。

smtp类发送邮件的方法其实很简单，也很稳定，类是别人已经写好的了，你只需要调用就行了。几行简单的配置就能发邮件，是不是很期待的试一试呢！

以下就是核心代码：

sendmail.php:

<?php require_once "email.class.php"; $smtpserver = "smtp.163.com";//SMTP服务器 $smtpserverport =25;//SMTP服务器端口 $smtpusermail = "test@163.com";//填写SMTP服务器的用户邮箱 $smtpemailto = 'mahuateng@QQ.com';//发送给谁 $smtpuser = "test";//SMTP服务器的用户帐号(去除@包括@后面的字符，比如test@163.com，那么此处写test) $smtppass = "********";//SMTP服务器的用户密码，不是邮箱的登录密码，而是开通POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务的授权码 $mailtitle = 'test mail is ok?';//邮件主题 $mailcontent = "<h1>Test email</h1>";//邮件内容 $mailtype = "HTML";//邮件格式（HTML/TXT）,TXT为文本邮件 $smtp = new smtp($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. $smtp->debug = false;//是否显示发送的调试信息 $state = $smtp->sendmail($smtpemailto, $smtpusermail, $mailtitle, $mailcontent, $mailtype);email.class.php:
