in PHP using PDO currently i have the following class to get the above output how can i change it to get the below output using PHP PDO:在使用 PDO 的 PHP 中，目前我有以下类来获得上述输出，我如何更改它以使用 PHP PDO 获得以下输出：

public function totalUpdates($friend,$session,$var_id, $g, $load) 
{
    try{
 $sql2="select distinct g.gp_id ,g.pid,g.author_gp,g.gname,g.type as ty1,g.title as tit1,g.data as dat1,g.pdate,g.group_id,g.author_id,"
            . "up.update_id as up1,up.update_body,up.time,up.title as tit2,up.account_name,up.author,up.type as ty2,up.data as dat2 "
            . "from group_posts as g "
            . "join updates as up on g.author_id=up.user_id_u"
            . " where "
            . "g.gname=:g "
            . "and up.update_id not in(:update_id_all)  and up.author in(:friend, :session) order by time,pdate desc limit $load,5";
$stmth=  $this->_db->prepare($sql2);//Check here syntax of $db 
      
    $stmth->bindValue(":friend",$friend);
    $stmth->bindValue(":session",$session);
    $stmth->bindValue(":update_id_all",$var_id);
   $stmth->bindValue(":g",$g);
    $stmth->execute();
   return $stmth->fetchAll(PDO::FETCH_ASSOC);
    } catch (PDOException $ei){
        echo $ei->getMessage();
    }
}

if anyone knows hows how to do it pl let me know.(i'm not an expert in PHP or MYSQL)如果有人知道怎么做，请告诉我。（我不是 PHP 或 MYSQL 专家）

UPDATE:-更新：-

following @adams advice i created a stored procedure but the problem is now i don't know how to fetch values through php class function.按照@adams 的建议，我创建了一个存储过程，但问题是现在我不知道如何通过 php 类函数获取值。

i get the following result if i run this in phpmyadmin(click on the pic to enlarge):如果我在 phpmyadmin 中运行它，我会得到以下结果（点击图片放大）：

在此处输入图片说明

CALL timeline('shan2batman','aboutthecreator', @updates, @group_posts)

now this is the php class function i wrote to fetch results but it isn't while following this example现在这是我编写的用于获取结果的 php 类函数，但不是在执行此示例时

public function totalProcedures($friend_name,$session_id)
{
/*
 *query to fetch stored procedure 
 */    
try
{
    //executing the stored procedure
    $sql_sp="CALL timeline (:friend, :session,@updates, @group_posts)";
    $stmt_sp= $this->_db->prepare($sql_sp);
    $stmt_sp->bindValue(":friend",$friend_name);
    $stmt_sp->bindValue(":session",$session_id);
    $stmt_sp->execute();
    $rows=$stmt_sp->fetch(PDO::FETCH_ASSOC);
   
$stmt_sp->closeCursor(); // closing the stored procedure
    //trying to get values from OUT parameters.
     
    $stmt_sp_2=$this->_db->prepare("select @updates ,@group_posts");
    $stmt_sp_2->execute();
    return var_dump( $stmt_sp_2->fetch(PDO::FETCH_ASSOC));
 
} 
catch (PDOException $ei)
{
  echo $ei->getMessage();
    
}    
    
}

instantiating the class:实例化类：

$totalProcedures=$project->totalProcedures($imp_id,$session_uname);

UPDATE2:- After troubleshooting things with help i'm finally able to get the first tables result but not the second ones result. UPDATE2:- 在帮助下解决问题后，我终于能够得到第一个表的结果，而不是第二个结果。 I know i'm missing something but can't figure it out.我知道我错过了一些东西，但无法弄清楚。 Any help is appreciated任何帮助表示赞赏

here is the class function that fetches only updates values need to get group_posts value how to do it in pdo(phpmyadmin produces both results)这是只获取更新值的类函数需要获取 group_posts 值如何在 pdo 中执行（phpmyadmin 产生两个结果）

   public function totalProcedures($friend_name, $session_id) 
{
            /*
             * query to fetch stored procedure 
             */
            try {
                //executing the stored procedure
                $sql_sp = "CALL timeline (:friend,:session)";
                $stmt_sp = $this->_db->prepare($sql_sp);
                $stmt_sp->bindValue(":friend",$friend_name);
                $stmt_sp->bindValue(":session",$session_id);
                $stmt_sp->execute();
              
    do {
        try {
           $rows = $stmt_sp->fetchAll(PDO::FETCH_ASSOC);
           if ($rows) {
           return $rows;     
           } else {
               echo die().'no data try rows';   
           }
           
        } catch (PDOException $exc) {
            echo $exc->getMessage();
        }
    
        
    } while ($stmt_sp->nextRowset());
    
            } catch (PDOException $ei) {
                echo $ei->getMessage();
            }
        }

UPDATE2:- after referring to this stackoverflow page i changed the code to: UPDATE2:- 在参考此stackoverflow 页面后，我将代码更改为：

    public function totalProcedures($friend_name, $session_id) {
        /*
         * query to fetch stored procedure 
         */
        try {
            //executing the stored procedure
            $sql_sp = 
                    "CALL timeline (:friend,:session)"
                    ;
            $stmt_sp = $this->_db->prepare($sql_sp);
            $stmt_sp->bindValue(":friend",$friend_name);
            $stmt_sp->bindValue(":session",$session_id);
            $stmt_sp->execute();
          $row=$stmt_sp->nextRowset();
do {
    try {
       $rows = $stmt_sp->fetchAll(PDO::FETCH_ASSOC);
       if ($rows) {
       return $rows;     
       } else {
           echo die().'no data try rows';   
       }
       
    } catch (PDOException $exc) {
        echo $exc->getMessage();
    }

    
} while ($stmt_sp->nextRowset());

        } catch (PDOException $ei) {
            echo $ei->getMessage();
        }
    }

still not able to get results now even updates results is not coming up.现在仍然无法获得结果，即使更新结果也没有出来。 can soimeone point out where the mistake is.有人可以指出错误在哪里。 Ajax comes with a message of 200 but no results now. Ajax 带有 200 的消息，但现在没有结果。

You could use a stored procedure and run 2 select queries inside the stored procedure to return multiple arrays.您可以使用存储过程并在存储过程中运行 2 个选择查询以返回多个数组。 Read more here在这里阅读更多

stored procedures return multiple values 存储过程返回多个值
