在php中发送邮件有两种方法。一种是用php自带的mailto()函数，但是这个需要额外的配置php.ini,还需要包含一个类，不易成功，还有就是兼容性不好。
另外一种是是用socket发送，这个似乎更麻烦，但是幸好有很多已经写好的类，只要调用即可相对而言就变简单了，兼容性也是极好的。下面是本人用的一个案例，写在下面了，希望可以帮到 有需要的朋友。

在文件中引入上面这个文件类，具体发送的代码如下：
1 if(isset($_POST[‘mail‘])){ 2 $smtpserver = "smtp.163.com";//SMTP服务器 这里用的是163的 3 $smtpserverport =25;//SMTP服务器端口 4 $smtpusermail = "***********@163.com"; //SMTP服务器的用户邮箱 在163注册的邮箱账号 5 $smtpemailto = "***********@qq.com"; //发送给谁 6 $smtpuser = "[email protected]"; //SMTP服务器的用户帐号 7 $smtppass = "***********"; //SMTP服务器的用户密码 在163注册的邮箱账号密码 8 $mailsubject = "Test Subject";//邮件主题 9 $mailbody = "尊敬的会员，".$_POST[‘user_name‘]."：<br />您的商品已成功兑换。订单号：".$_POST[‘orderId‘]."，运单号:".$_POST[‘exp ressId‘].",快递公司：".$_POST[‘express_name‘]."。";//邮件内容 10 $mailtype = "HTML";//邮件格式（HTML/TXT）,TXT为文本邮件 11 $smtp = new smtp($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. 12 $smtp->debug = FALSE;//是否显示发送的调试信息 13 if($smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)){ 14 //邮件发送成功以后，设置为已经处理 15 $sql="update dou_exchange set exchange_status=1 where id=:id"; 16 $stmt=$pdo->prepare($sql); 17 $stmt->bindParam(‘:id‘, $_POST[‘id‘]); 18 $stmt->execute(); 19 echo "<script>alert(‘已发送成功兑换邮件！‘);</script>"; 20 }else{ 21 echo "发送邮件失败"; 22 exit;}
