Question

I’m struggle extracting necessary data from this json stored inside php variable.
Not yet expert in this kind of data structure yet…

Wondering anyone know how to make it work.

I need to loop through results, then read each contact to get
1. the value where type=email
2. value->givenName where type=name (whenever element exist)

the json decoded value is as below

$aNative   = json_decode($retval);

echo "lang: " . $aNative->query->lang . "<br>"; (works)    

(when go deeper, fail to retrieve any value...)

echo "created: " .  $aNative->results->contact[0]->created . "<br>";


foreach($aNative->$query->results as $contact)
{
    echo $contact->id;
    echo $contact->fields[0]->type;

    if($contact->fields[0]->type=="email")
    {
        echo $contact->fields[0]->value;
    }

}

full json:

{
   "query":{
      "count":10,
      "created":"2012-06-13T09:13:45Z",
      "lang":"en-US",
      "results":{

         "contact":[

Answer 1

You have forgotten about query. You have to access to results for example in this way:

$aNative->query->results->contact[0]->created

And review whole your code you are trying to access to wrong properties many times. For example in foreach you shall use $aNative->query->results->contact instead of $aNative->results because results it is an object and not array.
