三 首页新闻发布,让你更新更轻松(中)

上次我们做了一个文件头(至于文件尾,请大家自己做,假设为tail.php),一个函数的模块,现在,我们来一个基本功能的实现,也就是动态发布啦

include("makestr.php";
include("head.php");
$newspath="/announce/"; //以文本文件存放的新闻文件的目录
$newsfile=array();//准备新闻数组
$hd=dir($newspath); //目录句柄
while($filename=$hd->read()){ //获取全部文件
$s=strtolower($filename);
if(strstr($s,".txt")){
//检测最新的修改日期
$lastchanged=fileatime($newspath.$filename);
$newsfile[$filename]=$lastchanged;
}
}
arsort($newsfile); //文件按时间排序
//输出文件
for(reset($newsfile);$key=key($newsfile);next($newsfile))
{$fa=file($newspath.$key);
$n=count($fa);
echo "

".date("d.m.Y-H:i:s".$newsfile[$key])."
\n";
for($i=0;$i$s=chop($fa[$i]);//去除空格
$s=htmlspecialchars($s);
print $s."

\n";

}
}
$hd->close(); //释放句柄
include("tail.php");  
?>
这样,将你的新闻文本传上你根目录的annouce子目录下,就可以方便发布新闻了。但真正的方便还不在于这,比如说,当新闻过时的时候,程序能自动删除它,多好。不用ftp,直接在线写下要新发的公告,多方便。好了,且听下回分解。
