如何在单个php页面中调用多个sql存储过程

Question

我正在尝试在同一页面中调用两个 sql 存储过程 我试过的是

                  mysqli_query($con,"DROP PROCEDURE IF EXISTS count_nodes_all_1 "); 
                  mysqli_query($con,"CREATE PROCEDURE count_nodes_all_1()
                               BEGIN
                                  CALL count_nodes_left_1('id-1',750);
                                  CALL count_nodes_right_1('id-2',750);
                                END"); 

                          $qry = "CALL count_nodes_all_1";                     

   if ($result = mysqli_query($con, $qry)) 
                  {
                    while ($row = mysqli_fetch_array($result)) 
                    {
                          
                          
                          
                             $total_left_1 = $row['total_left_1'];
                             $total_right_1 = $row['total_right_1'];
                          
?>
      <th scope="row"><?php echo number_format($total_left_1); ?></th>
      <th scope="row"><?php echo number_format($total_right_1); ?></th>

这里$total_left_1 = $row['total_left_1']; 是第一个过程的输出，$total_right_1 = $row['total_right_1']; 是第二个过程的输出 现在，问题是我得到了<?php echo number_format($total_left_1); ?> 的输出并且无法得到<?php echo number_format($total_right_1); ?> 的输出它只是显示Notice: Undefined index: total_right_1 in G:\XampNew\htdocs 请在这方面帮助我

你需要使用 mysqli_fetch_array 两次
