Question

I’m completely noob with json.

I need to parse a json that returns a result like this:

"response":{
    "status":1,
    "data":{
      "16":{
        "Offer":{
          "id":"16",
          "advertiser_id":null,
          "name":"My Offer",
          "description":null,
          "require_approval":"0",
          "require_terms_and_conditions":0,
          "terms_and_conditions":null,
          "offer_url":"http://",
          "preview_url":"http://",
        }
      },
      "17":{
        "Offer":{
          "id":"17",
          "advertiser_id":null,
          "name":"My Other Offer",
          "description":null,
          "require_approval":"0",
          "require_terms_and_conditions":0,
          "terms_and_conditions":null,
          "offer_url":"http://",
          "preview_url":"http://",
        }
      },
    },
    "errors":[]
  }

I need to access all offers name, but I’m not able to access trying this :

$url = "jsonurl";

$string = file_get_contents($url);
$json_a=json_decode($string,true);

foreach ($json_a['data']['offer'] as $offer_a) {
  echo  $offer_a[name];
}

What I’m doing wrong ??

thank you all in advance.

Answer 1

You seem to be skipping the 16. But this is easily debugged by doing this.

echo '<pre>';
print_r($json_a);
die();

This will display the tree in an array/object. In this case an array.

But I guess this will work:

foreach ($json_a['response']['data']['16']['Offer'] as $offer_a) {
  echo  $offer_a['name'];
}

If you need all offer names:

foreach ($json_a['response']['data'] as $offer){
    echo $offer['Offer']['name'];
}
