发布时间:2020-10-28编辑:脚本学堂
分享一个php邮件发送类,包括php类文件与测试示例,借助smtp发送邮件,可以设置smtp服务器、smtp端口、smtp用户名与密码,需要的朋友参考下。

一个简单的PHP邮件发送类,一共包含两个文件。

1,文件 sent_mail.php
 

 

复制代码 代码示例:

<?php 
require_once ('email.class.php');

$smtpserver = "smtp.163.com";//SMTP服务器
$smtpserverport =25;//SMTP服务器端口
$smtpusermail = "xxx@163.com";//SMTP服务器的用户邮箱
$smtpemailto = "xxx@qq.com";//发送给谁
$smtpuser = "xxx@yuju100.com";//SMTP服务器的用户帐号
$smtppass = "*****";//SMTP服务器的用户密码
$mailsubject = "PHP100测试邮件系统";//邮件主题
$mailbody = "<h1> 这是一个测试程序 PHP100.com </h1>";//邮件内容
$mailtype = "HTML";//邮件格式(HTML/TXT),TXT为文本邮件

//--调用方法
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//true是表示使用身份验证,否则不使用身份验证.
$smtp->debug = true;//是否显示发送的调试信息
$smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
?>

2,php发邮件的类 email.class.php
