定义索引和 if 语句

我正在尝试将 JSON 文件的集合映射到 mysql 数据库，这里是 json 的示例：

{
    "fileVersion": "1.0",
    "configurationItems": 
[
{
    "configurationItemVersion": "1.0",
    "configurationItemCaptureTime": "2014-12-12T17:14:09.005Z",
    "configurationStateId": 32,
    "relatedEvents": 
[
    "42d9f9c9-121c-4053-9ea8-451e98eeaf83"
],
"awsAccountId": "",
"configurationItemStatus": "OK",
"resourceId": "",
"ARN": "arn:aws:ec2:us-east-1:037734006438:vpc/vpc-ab8390c9",
"awsRegion": "us-east-1",
"availabilityZone": "Multiple Availability Zones",
"configurationStateMd5Hash": "",
"resourceType": "AWS::EC2::VPC",
"tags": { },
"relationships":
[
{

使用以下 php 我得到一个未定义的索引 AWS：：EC2：：VPC 错误：

$con=mysqli_connect("localhost","root","","json_map");
$response = array();

$result='' ;
foreach(glob('C:'xampp'htdocs'laravel'awsconfig'app'views'*.json') as $filename)
{
    $json = file_get_contents($filename);
    if($json!=null)
    { 
        $decoded=json_decode($json,true); 
        //$decode= var_dump($decoded); 
        //$ss=$decode["array"]; 
        //echo $decoded['number']; 
        if(is_array($decoded["configurationItems"]))

                    if ($result)

                        $response["code"] = 1; 
                        $response["message"] = "successfully updated configuration items volume"; 
                        // echoing JSON response

                    else
                    { 
                        echo mysql_error();
                        // failed to insert row 
                        $response["code"] = 2; 
                        $response["message"] = "Oops! An error occurred.";

                        echo json_encode($response); 
                    } 
                } 
            } 
        }
    }
}
?> 

我认为这是工作的方式是，如果资源类型等于 VPC 或其他类型的类型（例如实例或安全组），则适当的数据将放入正确的表中，谢谢
