目标是最终得到一个组合数组（如下例所示），其中两个数组已递归组合以维护数组键结构，但返回值的总和：

        [2016-09-15] => 0
        )
    )
)

我试过跟随代码，但输出没有返回预期的值：

foreach ($array as $value){
  $id = $value[];
   if ( !isset($output[$id]) ) {
     $output[$id] = array();
   }
   $output[$id] = array_merge($output[$id], $value);
}

任何帮助都将不胜感激。

Answer 1

如果我理解你的问题，那么这就是你如何组合你的数组：

function merge($arr1, $arr2)
{
    $arr = [];

    foreach ($arr1 as $key => $value) {
        if (is_array($arr1[$key])) {
            $arr[$key] = merge($arr1[$key], $arr2[$key]);
        } else {
            $arr[$key] = $arr1[$key] + $arr2[$key];
        }
    }

    return $arr;
}

Answer 2

您可能希望使用函数array_merge_recursive来合并2个数组。

$newarray = array_merge_recursive($array1, $array2);

然后你需要遍历你的新数组并递归搜索键0和1，并添加它们的值。
