怎么从Json中取出数据放到一个新组中

{
    "CommunityModel": [
        {
            " UUID ": "xxxxxx-xxxxxx-xxxxxxx-xxxxxx1",
            " CommunityName ": "格林花园",
            " CommunityAddress ": "XXXX203号",
            " Longitude ": "12.33333333",
            " Latitude ": "143.1121222",
            " Form ": "商品房",
            " BuildingNum ": "100",
            " OwnerNum ": "1800",
            " CarportNum ": "1800"
        },
{
            " UUID ": "xxxxxx-xxxxxx-xxxxxxx-xxxxxx2",
            " CommunityName ": "格林花园2",
            " CommunityAddress ": "XX路203号",
            " Longitude ": "12.33333333",
            " Latitude ": "143.1121222",
            " Form ": "商品房",
            " BuildingNum ": "100",
            " OwnerNum ": "1800",
            " CarportNum ": "1800"
        }
    ]
}

		
                $url_get ='http://api.com:90/1.php';
		$json=json_decode($this->curlGet($url_get));
		foreach($json as $jsonvalue)
		{
                      。。。。这里该如何写
	//		dump($jsonvalue);
		}

$s =<<< JSON
{
    "CommunityModel": [
        {
            " UUID ": "xxxxxx-xxxxxx-xxxxxxx-xxxxxx1",
            " CommunityName ": "格林花园",
            " CommunityAddress ": "XXXX203号",

            " CarportNum ": "1800"
        }
    ]
}
JSON;
$a = json_decode($s, 1);
foreach($a['CommunityModel'] as $v) {
  $arr[] = array('UUID' => $v[' UUID '], 'CommunityName' => $v[' CommunityName ']);
}
print_r($arr);

Array
(
    [0] => Array
        (
            [UUID] => xxxxxx-xxxxxx-xxxxxxx-xxxxxx1
