需要用PHP发送邮件,不想要phpmailer那么复杂,找来找去,总算找到了一个好用的,分享出来,代码如下.
PHP邮件发送类,一共包含两个文件.
sent_mail.php
- <?php
- require_once ('email.class.php');
- //##########################################
- $smtpserver = "smtp.163.com";//SMTP服务器
- $smtpserverport =25;//SMTP服务器端口
- $smtpusermail = "[email protected]";//SMTP服务器的用户邮箱
- $smtpemailto = "[email protected]";//发送给谁
- $smtpuser = "[email protected]";//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
- ##########################################
- $smtp = new smtp($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 = true;//是否显示发送的调试信息
- $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
- ?>
