<?php

//以下建立一文本文档，其值自动计数
$countfile="count.txt";

}
$fp=fopen($countfile,"r");

fclose($fp);
$fp=fopen($countfile,"w");
fwrite($fp,$num); //更新其值
fclose($fp);

//利用上面自动计数的值获得HTML的路径$path
$houzui=".html";
$path=$num.$houzui;
//这样形成的路径是自动增长的，如1.html,2.html,3.html……….添加一条新闻便自动加上1

//以下用SQL语句添加数据至表 news
$sql="insert into news (id,title,content,path) values ('','".$title."','".$content."','".$path."')";
$query=mysql_query($sql);

//以下为关键之处，把从表单获得的数据替换模板中的{title},{content}标记
$fp=fopen("mode.html","r"); //只读打开模板
$str=fread($fp,filesize("mode.html"));//读取模板中内容
$str=str_replace("{title}",$title,$str);
$str=str_replace("{content}",$content,$str);//替换内容
fclose($fp);

$handle=fopen($path,"w"); //写入方式打开新闻路径
fwrite($handle,$str); //把刚才替换的内容写进生成的HTML文件
fclose($handle);

//收尾工作:
echo "<a href=$path target=_blank>查看刚才添加的新闻</a>";
