Get a specific value in JSON

Question

I'm wondering how do i access the 3rd "value" using PHP in the following:

   "data": [
      {
         "id": "-",
         "name": "-",
         "period": "-",
         "values": [
            {
               "value": 0,
               "end_time": "2011-10-08T07:00:00+0000"
            },
            {
               "value": 0,
               "end_time": "2011-10-09T07:00:00+0000"
            },
            {
               "value": 0,
               "end_time": "2011-10-10T07:00:00+0000"
            }
         ]

As for now I'm trying to do something with:

$results = json_decode(curl_exec ($curl));

But then I'm stuck because there are 3 "value" inside of "values" and to tell you the truth I'm pretty confused..

What about `$results->data->values[2]` (object property, array)? — hakre, Oct 12 '11 at 09:09

use `print_r()` or `var_dump()` to see what the decoded array/object looks like. You should be able to work out how to access variables in it from that. — Spudley, Oct 12 '11 at 09:19

this code is just for your understanding you can get the better idea from this.

<?php

$json = '[{"id": "-","name": "-","period": "-","values": [{"value": 0,"end_time": "2011-10-08T07:00:00+0000"},{"value": 0,"end_time": "2011-10-09T07:00:00+0000"},{"value": 0,"end_time": "2011-10-10T07:00:00+0000"}]}]';

$jasondata =json_decode($json,true);

echo $jasondata[0]['values'][2]['value']; exit;

echo "<pre>"; print_r($jasondata); exit;
?>
