Get JSON objects in PHP, not array -

im writing website in php gets jsonstring php-api ive created. string looks this:

{     "result": "true",     "results": {         "20": {             "id": "20",             "desc": "a b ct tr",             "active": "1",             "startdate": "2013-04-03",             "starttimehour": "18",             "starttimemin": "0",             "enddate": "2013-04-03",             "endtimehour": "22",             "endtimemin": "0",             "creator": "a"         },         "21": {             "id": "21",             "desc": "test",             "active": "0",             "startdate": "2013-04-04",             "starttimehour": "18",             "starttimemin": "0",             "enddate": "2013-04-04",             "endtimehour": "22",             "endtimemin": "0",             "creator": "a"         }     } } 

ive found lots of answers on how information jsonarray im not using array here. question is: how can objects labeled 20, 21 , forth(these numbers generated server dont know ones returned).

or should rewrite how api returns json array instead. this:

{"result"="true", "results":[{...},{...},{...}]} 

$json = json_decode($json_string, true); foreach($json['results'] $key => $value) {     // access number $key , associated object $value     echo 'number: '.$key;     echo 'startdate: '.$value['startdate']; }
