如何将数组转换为json解码格式

Question

我想将我的数组转换为 JSON 格式，我该怎么做。 下面是我的代码

    $arr['more_images'][] = $datas;
    echo '<pre>';
    print_r($arr['more_images']);
    echo '</pre>';
In above code i am getting output like this
<pre>Array
(
    [0] => Array
        (
            [0] => http://sale4allz.com/sale4allz/public/uploads/product_more_images/178_3749.jpg
            [1] => http://sale4allz.com/sale4allz/public/uploads/product_more_images/178_4923.jpg
            [2] => http://sale4allz.com/sale4allz/public/uploads/product_more_images/178_9362.jpg
        )

)
</pre>
But I want output like this

        [
          {
               http://sale4allz.com/sale4allz/public/uploads/product_more_images/178_3749.jpg
    }
          {    http://sale4allz.com/sale4allz/public/uploads/product_more_images/178_4923.jpg
    }
          {    http://sale4allz.com/sale4allz/public/uploads/product_more_images/178_9362.jpg
            }
    ]

我该怎么做？如果有人知道解决方案，请告诉

Answer 1

你应该使用以下逻辑：

header('Content-Type: application/json');
echo json_encode( $arr['more_images']);

Answer 2

你应该试试这个：

$arr['more_images'][] = json_encode($datas);
    echo '<pre>';
    print_r($arr['more_images']);
    echo '</pre>';

或

$arr['more_images'][] = $datas;
        echo '<pre>';
        print_r(json_encode($arr['more_images']));
        echo '</pre>';
