PHP合并数组子项

Question

I've seen several questions and answers on this but none that seem to do what I need. Basically I have:

Array1:

[2014-1-1]
    [0]
        'goodthings' = 9

Array2:

[2014-1-1]
    [0]
        'badthings' = 2

and I want to create:

resultarray:

[2014-1-1]
    [0]
        'goodthings' = 9
        'badthings' = 2

Where [2014-1-1] is a list of dates and [0] is the hours of the day... Seems like a simple request but I can't figure it out?

Answer 1

Unsure if this is exactly what you want, but

Using array_merge_recursive()

$array1 = [
    '2014-1-1' => [
        0 => ['goodthings' => 9]
    ]
];

$array2 = [
    '2014-1-1' => [
        0 => ['badthings' => 2]
    ]
];

$result = array_merge_recursive($array1, $array2);
var_dump($result);

gives

[ "2014-1-1" => [
    0 => [ "goodthings" => 9 ]
    1 => [ "badthings" => 2 ]
]
