在索引存在的情况下继续获取 'Undefined index'，在在线编辑器中完美运行但在项目中不运行？

Question

我正在使用 php、laravel 和 Vue (&vuex) 创建仪表板。 Whosebug 的另一个用户给了我很大的帮助，并提出了以下代码来从我从 [=47= 返回的数据集中提取我想要的值（仅 'Result' 和 'result'） ] API。他的代码似乎在每个在线 PHP 编辑器中都能完美运行。但是一旦我想尝试在我的项目中使用它，我就会收到一条错误消息，上面写着“未定义的索引：结果”。是什么原因造成的，我该如何解决？

我似乎无法解决这个问题。任何帮助将不胜感激！

代码：

$data = Log::all('RESPONSE');
$results_decoded = json_decode($data, true);

foreach ($results_decoded as $inner_val){
            if (isset($inner_val["Result"][0]["ERRORS"])) $result_array[] = $inner_val["Result"][0]["ERRORS"];
            else $result_array[] = $inner_val['result'];

        }

        return json_encode($result_array);

var_export() - 数据集：

$results_decoded = array ( 
0 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211049', ), ), ),
1 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211048', ), ), ), 
2 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211050', ), ), ), 
3 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211050', ), ), ), 
4 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211049', ), ), ), 
5 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211046', ), ), ), 
6 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211045', ), ), ), 
7 => array ( 'result' => '2007: New Web Order created successfully', ), 
8 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211046', ), ), ));

期望的结果数组：

["99012: Weborder number already exists : 20211049",
"99012: Weborder number already exists : 20211048",
"99012: Weborder number already exists : 20211050",
"99012: Weborder number already exists : 20211050",
"99012: Weborder number already exists : 20211049",
"99012: Weborder number already exists : 20211046",
"99012: Weborder number already exists : 20211045",
"2007: New Web Order created successfully",
"99012: Weborder number already exists : 20211046"]

我的代码（在项目中使用）：

        $data = Log::all('RESPONSE');
        $results_decoded = json_decode($data, true);

        $result_array = [];
        foreach ($results_decoded as $inner_val){
            if (isset($inner_val["Result"][0]["ERRORS"])) $result_array[] = $inner_val["Result"][0]["ERRORS"];
            else $result_array[] = $inner_val['result'];

        }

解释：

如果我做对了，并且数组键在您描述的数组中是 Result 和 result，那么这段代码就是正确的。

$results_decoded = array ( 
0 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211049', ), ), ),
1 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211048', ), ), ), 
2 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211050', ), ), ), 
3 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211050', ), ), ), 
4 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211049', ), ), ), 
5 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211046', ), ), ), 
6 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211045', ), ), ), 
7 => array ( 'result' => '2007: New Web Order created successfully', ), 
8 => array ( 'Result' => array ( 0 => array ( 'ERRORS' => '99012: Weborder number already exists : 20211046', ), ), ));

foreach ($results_decoded as $inner_val){
    $result_array[] = $inner_val["Result"][0]["ERRORS"] ?? $inner_val['result'] ?? '';    
}

$result_array = array_values($result_array);

echo json_encode($result_array);

Keep getting 'Undefined index' while index is there, Works perfectly in online editor but not in project?
