在PHP中处理JSON响应

Question

Using PHP, I have decoded this JSON Response..

Array ( [Request] => Array ( [RequestGuid] => 4ca35135-2560-42ef-bd63-6b22cbf369ed [PackageId] => c1bf0061-b0b7-4f71-8a9a-43d6e468e5ec [PackageVersion] => 2 [ResponseVersion] => 2 [DataKeys] => Array ( [Vrm] => KM14AKK ) ) [Response] => Array ( [StatusCode] => Success [StatusMessage] => Success [StatusInformation] => Array ( [Lookup] => Array ( [StatusCode] => Success [StatusMessage] => Success [AdviceTextList] => Array ( ) ) )

When I run...

  $data = json_decode($response, true);
  for ($i=0;$i<count($jsonArray);$i++){
    echo $jsonArray[$i];
  }

I get the error...

Notice: Undefined offset: 0

Any quick pointers as to how to access data in this feed, arrays always blag my head, I can see there is no key in this one?

Thanks.

Use foreach loop instead of for loop so change loop as:

$data = json_decode($response, true);
  for ($i=0;$i<count($jsonArray);$i++){
    echo $jsonArray[$i];
  }

To:

$data = json_decode($response, true);
foreach($data as $d){
   print_r($d); 
}

Here your $response JSON data does not have index value. It has keys and values pair. So you can not use index here.
