推荐答案

尝试以下解决方案:

$json = '[{"label":"Food & Drinks","data":"2"},{"label":"Lifestyle","data":"1"}]';

$json_array = json_decode($json, true);

$new_array = array();

foreach($json_array as $arr){
    $new_array[] = array_values($arr);
}

print_r($new_array);

echo json_encode($new_array);

输出:

Array
(
    [0] => Array
        (
            [0] => Food & Drinks
            [1] => 2
        )

    [1] => Array
        (
            [0] => Lifestyle
            [1] => 1
        )

)
[["Food & Drinks","2"],["Lifestyle","1"]]
