从Json中获取数组？

Question

I am getting a Json respond with :

$response = curl_exec($rest);  
 $json = json_decode($response, true);

I manage to get its values(strings) with :

$foundUserId=$json['results'][0]['userId'];
$foundName=$json['results'][0]['name'];
$foundPhoneNum=$json['results'][0]['phoneNumber'];

But the last value- phoneNumber, is array of strings .

If i try then to loop over it i get nothing(although the array is there in the Json)

  foreach ($foundPhoneNum as &$value) 
    {
      print_r($value);

    }

What am i doing wrong ?

EDIT : The json:

Array ( [results] => Array ( [0] => Array ( [action] => message [createdAt] => 2015-11-21T09:36:33.620Z [deviceId] => E18DDFEC-C3C9 [name] => me [objectId] => klMchCkIDi [phoneNumber] => ["xx665542","xxx9446"] [state] => 1 [updatedAt] => 2015-11-22T08:24:46.948Z [userId] => 433011AC-228A-4931-8700-4D050FA18FC1 ) ) )

You might have json as a string inside json. That's why after json_decode() you still have json inside phoneNumber. You have 2 options:

• Decode phoneNumber like

  $foundPhoneNum=json_decode($json['results'][0]['phoneNumber']);
  

• Build proper initial json. Instead of

  {"phoneNumber": "[\"xx665542\",\"xxx9446\"]"}
  

  should be

  {"phoneNumber": ["xx665542","xxx9446"]}
