代码如下：

我们可以用新闻系统来存储新闻，我们可以对新闻进行添加、删除等操作，这样减少了大家的工作量，为什么不实验一下。

首先，建立一个表。
create table news (
n_id int(255) not null auto_increment,
n_date datetime not null,
news text not null,
primary key(n_id)
);

第二步，设置你的登陆信息
$database_user_name="root";                         
$database_password="";                                                 
$database_name="news";                              
$time_offset="0";

第三步，让我们把后面程序用到的东西作成函数，节省篇幅啊！

function connect_db()
    {
    // connects to the database
     
    global $database_user_name, $database_password;
    $db=mysql_connect("localhost",$database_user_name,$database_password);
         
    return $db;
     
    }


function db_name()
    {
    // returns the name of the database
     
    global $database_name;
    $db_name=$database_name;
     
    return $db_name;
     
    }
     
     
     
function get_now()
    {
    // gets current date and time
     
    $db=connect_db();
    $db_name=db_name();
    mysql_select_db($db_name,$db);
    $sql="select now() as now";
    $result=mysql_query($sql,$db);
    $myrow=mysql_fetch_array($result);
    $now=$myrow["now"];
     
    return $now;
     
    }
第四步，让我们考虑如何将新闻显示出来


//上面已经定义的函数库...
//表格的定义......
$title ";
if ($admin==1)
    {
     
    echo " Admin ";
    }  
     
echo " - News

";


$db=connect_db();
$db_name=db_name();
mysql_select_db($db_name,$db);

if ($show_news_sub)
    {
     $show_news = $show_news_sub;
    }
     

if (!ereg("([0-9]{".strlen($show_news)."})",$show_news))
    {
    $show_news="ALL";
    }

if (strtoupper($show_news)=="ALL")
    {
     
    $sql="select date_format(n_date,'%m/%d/%Y') as n_date, date_format(n_date,'%H:%i') as n_time ,news , n_date as date from news order by date desc";
     
    }
else  
    {
     
    $link="All news";
     
     
    $sql="select date_format(n_date,'%m/%d/%Y') as n_date, date_format(n_date,'%H:%i') as n_time , news , n_date as date from news order by n_date desc limit $show_news";
    }
$result=mysql_query($sql,$db);
$num_rows=mysql_num_rows($result);
if($num_rows!=0)
    {
echo "


";

    while($myrow=mysql_fetch_array($result))
        {
        $date=$myrow["n_date"];     
        $time=$myrow["n_time"];         
        $news=$myrow["news"];
        $n_id=$myrow["n_id"];
        if (strtoupper($show_date)=="Y" && strtoupper($show_time)=="Y")
            {
            $show=$date." ".$time;
             
            }
        else if (strtoupper($show_date)=="Y" && strtoupper($show_time)!="Y")     
            {
            $show=$date;
             
            }
        if (strtoupper($show_date)!="Y" && strtoupper($show_time)=="Y")
            {
            $show=$time;
             
            }     
             
        $cleannews=(nl2br($news));

  
$show
$cleannews



";
}
echo "     

";

         


    }
if ($admin==1)
{
echo "
返回
";
}

if ($link)
    {
    echo "

$link";
     
    }
说明：省略了格式方面的标签，这样看起来思路清晰些，你可要加上啊
