This article mainly introduces the steps and methods to implement the message board function in PHP. Has very good reference value. Let’s take a look with the editor below

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];
}
}
?>

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

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