PHP关联数组合并键

Question

I am working to combine the following arrays:

Array #1

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

The goal is to end up with a combined array (like the example below) in which both arrays have been combined recursively to maintain the array key structure, but return the sum of values:

Combined Array

        )
    )
)

I have tried to following code, but the output does not return the expected values:

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

Any help would be appreciated.

Answer 1

if i understand your question correctly, then this is how you can combine your arrays:

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;
}
