将 php 多维数组编码为 json

Question

我在尝试将多维数组编码为 json 时遇到问题。如何删除密钥“0”和“1”？'

这是我的代码

$ch_name = count($app->request->post('ch_name'));
        for ($i=0; $i < $ch_name; $i++) {
            $min = count($app->request->post('minim_channel_'.$i));
            for ($j=$min - 1; $j >= 0; $j--) { 
                $gros[$j] = array('min' =>$app->request->post('minim_channel_'.$i)[$j], 'price' => $app->request->post('harga_channel_'.$i)[$j]);
            }
            $prices[$i] = array('channel' => $app->request->post('ch_name')[$i], 'price' => $app->request->post('harsat_channel_'.$i), 'grosir' => array($gros));
        }

        echo json_encode($prices);

这是结果

[{"channel":"Tokopedia","price":"10000","grosir":[{"1":{"min":"3","price":"9500"},"0":{"min":"10","price":"9000"}}]},{"channel":"Lapak","price":"10500","grosir":[{"1":{"min":"3","price":"9700"},"0":{"min":"10","price":"9200"}}]}]

您可以尝试更改代码的以下部分吗

for ($j=$min - 1; $j >= 0; $j--) { 
    $gros[$j] = array('min' =>$app->request->post('minim_channel_'.$i)[$j], 'price' => $app->request->post('harga_channel_'.$i)[$j]);
}

到

$gros = array();
for ($j=$min - 1; $j >= 0; $j--) { 
    $gros[] = array('min' =>$app->request->post('minim_channel_'.$i)[$j], 'price' => $app->request->post('harga_channel_'.$i)[$j]);
}

看看这是否符合您的要求。
