我的第一篇文章在这里的Stackoverflow.
在php中,如何正确地将两个不同数据点的JSON数组从两个独立的链接中读取到一个数组中?这里的目标是将两个独立的JSON数据集的值合并成一个数组,然后插入到MySql中。

Array 
(
    [1] => 'HourDK' value         // Dataset 1
    [2] => 'PriceArea' value      // Dataset 1
    [3] => 'SpotPriceDKK' value   // Dataset 1
    [4] => 'Price1' value         // Dataset 2
)

然后是24个数组,每小时一个,按"HourDK"排序。然后将这个数组插入MySQL。

因为数据集2中的数据点不能使用foreach循环,你可以使用for循环,通过$var['Price' . $num]得到这些值。请看下面的例子,如果它适合你,请告诉我。

<?php
    $hour_prices = array();

    for ($hour = 0; $hour < 24; $hour++) {
        $hour_prices[] = array(
            $dataset_1['records'][$hour]['HourDK']
            , $dataset_1['records'][$hour]['PriceArea']
            , $dataset_1['records'][$hour]['SpotPriceDKK']
            , $dataset_2['records'][0]['Price' . ($hour + 1)]
        );
    }
?>
