最近写的一个基于POP3协议 获取邮件的类

<?php
/*
说明： 获取邮件内容
方法： Pop3 () 构造函数    $getMail = new Pop3("pop.qq.com","5847999","*****",110); $getMail -> getEmails(); $getMail -> getEmail(10);
      login() 登陆方法
      logoff() 退出方法
      _strip_clf() 处理文本方法 一个私有的 为了测试 没有定义成私有
      getEmailHeaders() 获取邮件头
      getEmail($num) 获取用户输入邮件条数内容
      getEmails() 调用这个以后获取所有文件   返回一个数组 打印数组查看内容 然后操作数组
     
   foreachr($getMail -> $massages as $msg)
   {
       $msg -> to;
     ...
     ...
     ...
     ...
   }
