首先当然要去下载phpmailer了。

<?php
  require("class.phpmailer.php"); //下载的文件必须放在该文件所在目录
    
  class email {
  public static $email;
    
  public function __construct($host,$Username,$Password,$Port=25,$charSet='UTF-8'){
  self::$email = new PHPMailer(); //建立邮件发送类
  self::$email->charSet=$charSet;//设置编码
  self::$email->IsSMTP();      //开启smtp服务
  self::$email->SMTPAuth = true; // 启用SMTP验证功能
  self::$email->Host = $host; // 您的企业邮局域名
  self::$email->Username=$Username; //账户
  self::$email->Password=$Password; //密码
  self::$email->Port=$Port;//端口,默认是25
    
  }
    
  public function sendEmail($From,$FromName,$AddAddress,$Subject,$Body,$name='',$AltBody='',$IsHTML=true){
  self::$email->IsHTML($IsHTML);//是否使用HTML格式
  self::$email->From=$From; //邮件发送者email地址 ,必须和上面的一致
  self::$email->FromName=$FromName; //邮件发送人的名字
  self::$email->AddAddress($AddAddress,$name);//邮件接收人的邮箱地址
  self::$email->Subject=$Subject;//主题
  self::$email->Body=$Body;//内容
  self::$email->AltBody=$AltBody;//附加信息,可以省略
    
  if(!self::$email->Send())
{
echo "邮件发送失败. <p>";
echo "错误原因: " . self::$email->ErrorInfo;
exit;
}
echo "邮件发送成功";
  }
    
    
   public function sendEmailAndAttachment($From,$FromName,$AddAddress,$Subject,$Body,$Attachment,$name='',$AltBody='',$IsHTML=true){
  self::$email->IsHTML($IsHTML);//是否使用HTML格式
  self::$email->From=$From; //邮件发送者email地址 ,必须和上面的一致
  self::$email->FromName=$FromName; //邮件发送人的名字
  self::$email->AddAddress($AddAddress,$name);//邮件接收人的邮箱地址
  self::$email->Subject=$Subject;//主题
  self::$email->Body=$Body;//内容
  self::$email->AltBody=$AltBody;//附加信息,可以省略
  self::$email->AddAttachment($Attachment); // 添加附件,这里填写附件地址
    
  if(!self::$email->Send())
{
echo "邮件发送失败. <p>";
echo "错误原因: " . self::$email->ErrorInfo;
exit;
}
echo "邮件发送成功";
  }
    
    
}
    
  $email =new email("smtp.qq.com",'371522155@qq.com','hh94577312');
  $email->sendEmailAndAttachment('371522155@qq.com','huanghui','2963584466@QQ.com','wwwww','vvvv','1.txt');
