如何摆脱PHP数组中设置的数字索引/键？

Question

如何摆脱以下数组中的数字索引：

    [0] => Array
    (
        [0] => Array
            (
                [ 2018:08:30-07:00:00 ] => 16.772925
            )

        [1] => Array
            (
                [ 2018:08:30-07:15:00 ] => 16.770355
            )

        [2] => Array
            (
                [ 2018:08:30-07:30:00 ] => 16.77907
            )

        [3] => Array
            (
                [ 2018:08:30-07:45:00 ] => 16.78735
            )
     )
    [1] => Array
    (
        [0] => Array
            (
                [ 2018:08:30-07:00:00 ] => 16.772925
            )
    )

看起来像这样：

 [0] => Array
 (
            [ 2018:08:30-07:00:00 ] => 16.772925
            [ 2018:08:30-07:15:00 ] => 16.770355
            [ 2018:08:30-07:30:00 ] => 16.77907
            [ 2018:08:30-07:45:00 ] => 16.78735
 )
 [1] => Array
 (
            [ 2018:08:30-07:00:00 ] => 16.772925
 )

我的php代码：

$time_to_priceee_1 = array();
$z_1 = 0;
foreach($pvt_1 as $pvtt_1)
{
    echo '1';
    $y_1 = 0;
    foreach($pvtt_1 as $pvttt_1 => $pvtttt_1)
    {
        $time_to_price_1[$z_1][$y_1] = $pvtttt_1['time'];
        $time_to_pricee_1[$z_1][$y_1] = $pvtttt_1['price'];
        $time_to_priceee_1[$z_1][$y_1] = array($pvtttt_1['time'] => $pvtttt_1['price']);
        $y_1 = $y_1 + 1;
    }

    $z_1 = $z_1 + 1;
}

$time_to_priceee_1的输出是我发布的第一个数组。那就是我似乎得到的。尝试过$time_to_priceee_1[$z_1]，$time_to_priceee_1，$time_to_priceee_1[]，$time_to_priceee_1[$z_1][$y_1] = array($pvtttt_1['time'], $pvtttt_1['price'])，但我认为我尝试的区域错误。

谢谢。

对不起，已经解决了。这是有效的代码：

$time_to_priceee_1[$z_1][$pvtttt_1['time']] = $pvtttt_1['price']; \

还是谢谢。
