导航JSON OBJ PHP

Question

I am trying to navigate this object, for example, getting where the query was successful? Then how would could I echo a list of the item's images? How would I go about doing that? Here is the object:

{"assets":[{"appid":"578080","contextid":"2","assetid":"629782983591116717","classid":"2225518126","instanceid":"0","amount":"1"},{"appid":"578080","contextid":"2","assetid":"629782983591116718","classid":"2225518127","instanceid":"0","amount":"1"},{"appid":"578080","contextid":"2","assetid":"629782983591116719","classid":"2225518128","instanceid":"0","amount":"1"},{"appid":"578080","contextid":"2","assetid":"629782983591116720","classid":"2225518129","instanceid":"0","amount":"1"},{"appid":"578080","contextid":"2","assetid":"629782983591116721","classid":"2225518130","instanceid":"0","amount":"1"},{"appid":"578080","contextid":"2","assetid":"629782983591116722","classid":"2225518131","instanceid":"0","amount":"1"},{"appid":"578080","contextid":"2","assetid":"629784346414177276","classid":"2225519077","instanceid":"0","amount":"1"},{"appid":"578080","contextid":"2","assetid":"1489972504775585911","classid":"2225519336","instanceid":"0","amount":"1"}],"descriptions":[{"appid":578080,"classid":"2225518126","instanceid":"0","currency":0,"background_color":"","icon_url":"8HAGSsiI9OXk0bu4o76O6xabNUY8RRLf00e56zWT3IZUH8Flab9goIFna_837oFuZVQurmh23qr2q44kS6_hSs5hYQ","icon_url_large":"8HAGSsiI9OXk0bu4o76O6xabNUY8RRLf00e56zWT3IZUH8Flab9goIFna_837oFuZVQurmh23qr2q44kS6_hSs5hYQ","descriptions":[{"type":"bbcode","value":"Basic costume.

Answer 1

You should use function json_decode:

$test = '{"assets":[{"appid":"578..."rwgrsn":-2}';
$objectTest = json_decode($test);
$arrayTest = json_decode($test, true);

var_dump($objectTest->success);
var_dump($arrayTest['success']);
