Simple PHP message board production

To make the basic message board function, you need three tables:

Employee table, message table, friend table

First create a login page:

 
帐号：
 
口令：
  

Above picture:

No need to say much, nothing wrong

Then write the processing page:

Query($sql); if(!empty($mi)&&$mi = $arr &&!empty($zhang)) { $_SESSION["zhang"] = $zhang; //即将跳转页面之前，把帐号存到session里面 header("location:zym.php"); } else { echo "登入失败了"; } ?>

The normal login page is just to save the account for a session

Log in and enter the main page

Then comes the main page:

    
  
留言板
 
发布信息
 
注销登入
 Query($sql); //取到登入的name echo "
欢迎你：{$attr[0][0]}
"; //输出登入的name $sql = "select * from liuyan WHERE shou = '{$zhang}' or shou = 'all' ORDER BY times DESC "; //条件！！我只看自己或所有人的 $arr = $db->Query($sql); foreach ($arr as $v){ $shou = aname($v[2]); $fa = aname($v[1]); //用方法 echo ""; } //返回姓名 function aname($zhang) { global $db; //设置全局变量！ if($zhang == "all") { //如果接收到的是all，显示： return "所有人"; } else { //如果是自己的，根据帐号查name $sql = "select name from yuangong WHERE zhang ='{$zhang}' "; $arr = $db->Query($sql); //二维数组 return $arr[0][0]; } } ?>

{$fa}
 
{$shou}
 
{$v[3]}
 
{$v[4]}
 
  

The search condition is to only search for your friends or everyone of all

Also note that the calling db should be set as a global variable

Picture:

The message board needs to publish information:

Publish information page:

    
  
发布信息
 Query($shaoyou); ?> 
 
 接收人:  所有 {$name}"; } ?> 
 
 
留言内容: 
 
   
 Query($sql); //二维数组 return $arr[0][0]; } } ?> 查看信息 注销登入  

##The last is the processing page for publishing information:

Query($sql,0)) { header("location:zym.php"); } else { echo "发布失败！"; }
