如何从数组中删除索引

Question

我有以下数组：

Array
(
    [relation] => AND
    [0] => Array
        (
            [relation] => AND
            [0] => Array
                (
                    [key] => restaurant_country
                    [value] => India
                    [compare] => ==
                )

            [1] => Array
                (
                    [key] => restaurant_city
                    [value] => East Delhi - Noida
                    [compare] => ==
                )

        )

    [1] => Array
        (
            [relation] => OR
            [0] => Array
                (
                    [key] => restaurant_price_min
                    [value] => 100
                    [compare] => <=
                )

            [1] => Array
                (
                    [key] => restaurant_price_min
                    [value] => 500
                    [compare] => <=
                )

        )

)

我想从上面的数组中删除索引。例如，我想要以下数组而不是上面的数据。

Array
(
    [relation] => AND
    Array
        (
            [relation] => AND
            [0] => Array
                (
                    [key] => restaurant_country
                    [value] => India
                    [compare] => ==
                )

            [1] => Array
                (
                    [key] => restaurant_city
                    [value] => East Delhi - Noida
                    [compare] => ==
                )

        )

    Array
        (
            [relation] => OR
            [0] => Array
                (
                    [key] => restaurant_price_min
                    [value] => 100
                    [compare] => <=
                )

            [1] => Array
                (
                    [key] => restaurant_price_min
                    [value] => 500
                    [compare] => <=
                )

        )

)

我想要这种格式的数组，因为wordpress查询以这种方式运行。

我没有得到如何做到这一点。

请帮帮我。

Answer 1

你想要的数组是不可能的，因为每个数组都有它的键，你不能删除它。

Answer 2

似乎是一个var_export显示器。 也许你试图用print_r来展示它？

即使3DR的答案是正确的，也是不可能的......
