Get item from json in PHP

Question

How to get the "duration" value from the below json in PHP :

{
 "kind": "youtube#videoListResponse",
 "etag": "\"6jI4SSPcXxEAc3i_1EQHOPi0Cvc/EGNSBh81ISlkeECbqD9xdh5C340\"",
 "pageInfo": {
  "totalResults": 1,
  "resultsPerPage": 1
 },
 "items": [
  {
   "kind": "youtube#video",
   "etag": "\"6jI4SSPcXxEAc3i_1EQHOPi0Cvc/yUebIRJfQ62Pq5XpRbqJHx7Xozo\"",
   "id": "7lCDEYXw3mM",
   "contentDetails": {
    "duration": "PT15M51S",
    "dimension": "2d",
    "definition": "hd",
    "caption": "true",
    "licensedContent": false,
    "contentRating": {
     "ytRating": ""
    }
   }
  }
 ]
}

Tried many examples but either it results in object error or invalid index error ?

Once json_decoded, you can say `['items']['contentDetails']['duration']` — Dave Chen, Sep 19 '13 at 12:17

$jsonObj  = json_decode($json);
$duration = $jsonObj->items[0]->contentDetails->duration;

or

$jsonArr  = json_decode($json, true);
$duration = $jsonArr['items'][0]['contentDetails']['duration'];

or in a loop:

$jsonArr  = json_decode($json, true);
foreach ($jsonArr['items'] as $item) {
    echo $item['contentDetails']['duration'];
}

Tested the first one and it works, thanks :). Any ideas how to convert the parsed "ISO 8601" duration into seconds ? – Stacked Sep 20 '13 at 05:29

Thanks, this did the trick : ```$interval = new DateInterval($duration); $tseconds = (($interval->format('%h')*60)*60)+($interval->format('%i')*60)+$interval->format('%s'); echo $tseconds;``` – Stacked Sep 20 '13 at 08:40
