PHP演示如何发送邮件给某个邮箱
首先，建立一个index.html文件，代码如下：
Simple Send Mail Mail Form
然后新建一个“mail.php”文档把传输的文档进行发送
debug = TRUE;//是否显示发送的调试信息 $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype); echo ""; exit; } ?>
最后编写一个邮件类“smtp.php”
debug = FALSE;
$this->smtp_port = $smtp_port;
$this->relay_host = $relay_host;
$this->time_out = 30; //is used in fsockopen()
$this->auth = $auth;//auth
$this->user = $user;
$this->pass = $pass;
$this->host_name = "localhost"; //is used in HELO command
$this->log_file = "";
$this->sock = FALSE;
}
