How to get returning associative array element from function?

public function getPhotos($id_album){
$hisPhoto = '123';
$myPhoto = '456';
$herPhoto = '789';
$id_user = 1;
$photoTable = array
(
    'hisPhoto' => $hisPhoto,
    'myPhoto' => $myPhoto,
    'herPhoto' => $herPhoto,
);
return array
(
    'id_user' => $id_user,
    'photos' => $photoTable
)
}
$photos = getPhotos($id_album);

我不知道如何在关联数组中使用关联数组。使用此函数访问我的照片(值"456"(的最简单方法是什么？

$photos最终将具有以下结构：

Array
(
'id_user' => $id_user,
'photos' => 
          Array
              (
                'hisPhoto' => $hisPhoto,
                'myPhoto' => $myPhoto,
                'herPhoto' => $herPhoto
              )
)

所以你可以去：

echo $photos['photos']['myPhoto'];

如果您坚持数组的结构，您可以使用：

print_r($array);
