Implementation ideas of using PHP to create a news system

We can use the news system to store news, and we can add and delete news. This reduces everyone's workload. Why not experiment with it.

First, create a table.
create table news (
n_id int(255) not null auto_increment,
n_date datetime not null,
news text not null,
PRimary key(n_id)
);

The second step is to set your login information
$database_user_name="root";                               $database_passWord="";                                    $database_name="news";                                     $time_offset="0";

The third step, let us make the things used in the subsequent program into functions to save space!

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;
​​​
}
The fourth step, let’s consider how to display the news


//The function library defined above...
//Definition of table...

$title ";
if ($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< /a>";
​​​
​​​
    $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
