这个类主要是为了读取邮件服务器中邮件的信息的，并对邮件信息进行处理，提取出邮件信息中的from，title ，content
并且提取出他们的编码格式，并对他们进行处理，同时from ，title 分别要和数据库中的信息去匹配，one_mail函数为只读取一封mail邮件的信息的，通过传参数i确定是读取第几封mail，并且返回mail 的 from ，title，content。在这个函数当中，主要是要判断当前的对象是否有parts属性，所以要进行判断，各个邮件发送邮件时候都有点差异的。编码的提取和解码
user_data函数主要是返回当前mail 参数中数据库中用户的信息，
insert_data函数，主要是把当前的当前的value 数据插入，value参数原为一个数组，后通过函数implode函数进行分解
，从而能对数据进行批插入。
reply_email函数为回复mai函数，这函数中主要的问题是要对发送过来的函数的编码进行提取，从而当回复时也用
它发送的编码方式，这样才不会出现编码的问题。
is_kid函数，为判断小孩是否是存在，和邮件信息时候相匹配
kid_message_count函数为孩子的大小排序的，如果当前孩子比较多的话，可以为它孩子进行大小排序。

执行这个类的话：
$file=fopen("mail.pid","a+");
if(flock($file,LOCK_EX+LOCK_NB)){
fwrite($file,date("Y-m-d H:i:s")."/tfile had locking/r/n");
$mail=new mail_data();
flock($file,LOCK_UN);
}else{
echo "程序运行中……";
}
fclose($file);

这个主要是通过文件锁flock来处理它进行单进程运行程序。

同时在整个类中，我也对当前的邮件信息数据进行了日志记载，和错误信息记录。
