删除Json编码额外的括号

我应该从JSON编码数据中删除额外的大括号吗

我得到了这个代码片段

{"":""
  {
   "primary_name":"ram",
   "primary_email":"ram@ramu.com",
   "primary_password":"1234",
   "primary_confirm_password":"1234",
   "title":"demo",
   "description":""
  }
""}

我希望我的代码看起来像这样

{
  "primary_name":"ram",
  "primary_email":"ram@ramu.com",
  "primary_password":"1234",
  "primary_confirm_password":"1234",
  "title":"demo",
  "description":""
 }

比宾先生 请试试这个

$json_obj = {"":""
              {
                "primary_name":"ram",
                ...

                "description":""
              }
          ""};

$new_array = [];

foreach( $json_obj as $item ){
    if( $item != ""){
      array_push($new_array, $item);
    } else {
      continue;
    }
}
