Json解码PHP

Question

im trying to extract the data inside the json file, but its not working, here is my code:

JSON:

{
   "list":[
      {
         "key":"12 ano",
         "value":"12 ano"
      },
      {
         "key":"12 ano administrativo",
         "value":"12 ano administrativo"
      },
      {
         "key":"12 ano contabilidade",
         "value":"12 ano contabilidade"
      }
   ]
}

PHP:

$url = 'what.json';
$content = file_get_contents($url);
$json = json_decode($content, true);
foreach($json as $i){
    echo $i['value'];
}

您必须在foreach中调用$json['list'] ，因为如果没有它，它将在仅包含列表数组的主数组上产生循环。
