多维数组作为变量保存在 dB 中

Question

我有一个多维数组

output_querys =  array(2) { [0]=> array(5) { ["ID"]=> string(1) "2" ["Code"]=> string(6) "AWS001" ["BCode"]=> string(4) "B001" ["Des"]=> string(4) "loan" ["subCat"]=> string(3) "SWA" } [1]=> array(5) { ["ID"]=> string(1) "4" ["Code"]=> string(6) "AWS002" ["BCode"]=> string(4) "B002" ["Des"]=> string(3) "tax" ["subCat"]=> string(3) "PJA" } }

我想把它取到一个变量中，然后保存到dB.I中，相关问题中提到的所有方法都试过了，都没有用。我得到的错误 1.trying 非对象 2.Illegal 字符串偏移量

我想做的是

foreach($output_querys as $output_query){
  $Pv_ID = $output_query->ID;
   $Pv_Code = $output_query->Code;
      $Pv_Description = $output_query->Des;
      
    
    $data_final = array(id => $Pv_ID, code => $Pv_Code, des => $Pv_Description);
                                                
      }
      db->insert(abc, $data_final);

这里有什么问题？？即使我尝试使用 json 编码，仍然显示“非法字符串偏移”

        $Pv_ID= json_decode($output_query['ID']);
                                       
        $Pv_Code = json_encode($output_query['Code'],true);
                                            
        $Pv_Description = json_encode($output_query['Des'],true);

我试过你给的数组和代码

    <?php
  $output_querys = array( 
    0 => array( 
            "ID" => "2", 
            "Code" => "AWS001", 
            "BCode" => "B001", 
            "Des" => "loan", 
            "subCat" => "SWA" 
    ),    
    1 => array( 
            "ID" => "4", 
            "Code" => "AWS002", 
            "BCode" => "B002", 
            "Des" => "tax", 
            "subCat" => "PJA" 
        )
);
  foreach($output_querys as $output){
    print_r($output['Code']); echo "\n";
    
  }
?>

我这边工作正常。 Here's the working example

我认为你也需要这样做，如果你想 1 乘 1 地插入然后将插入移动到 foreach 循环中

foreach($output_querys as $output_query){
  $Pv_ID = $output_query->ID;
   $Pv_Code = $output_query->Code;
      $Pv_Description = $output_query->Des;
      
    
    $data_final = array(id => $Pv_ID, code => $Pv_Code, des => $Pv_Description);
     db->insert(abc, $data_final);                                           
      }
