arrays - Parse a multi level json in php -

i have json file , "host_name" values items. below, php code, tried things, using true decode json in array or without , use foreach(), can't it.

{     "href": "https://webservice:8080",     "items": [         {             "hosts": {                 "cluster_name": "cluster1",                 "host_name": "server1"             },             "href": "https://server1:8080"         },         {             "hosts": {                 "cluster_name": "cluster1",                 "host_name": "server2"             },             "href": "https://server2:8080"         },         {             "hosts": {                 "cluster_name": "cluster1",                 "host_name": "server3"             },             "href": "https://server3:8080"         }     ] } 

here php code. simple possible. goal use last values of json ('host_name') display of them.

<?php         $content = file_get_contents("test.json");         $content = utf8_encode($content);         $result = json_decode($content, true);         var_dump($result);         echo "<br><br><br>";          #echo $result["items"]["hosts"][0]["host_name"];          foreach($result $r) {                 echo $r['items']['hosts']['cluster_name'].'<br>';         } ?> 

thanks.

you looping on wrong array, should be

foreach($result['items'] $item) {     echo $item['hosts']['host_name']; }
