Append the keys of an associative array as values of another array

Question

This seems simple yet I cannot figure it out. I need to return an array merge for 2 arrays, they are not exactly the same and one is a global multidimensional array.

$array1 = ['dogs' => __('Dogs'), 'cats' => __('Cats')];  // localized
$array2 = [
    'ducks' => ['width' => 350, 'height' => 350, 'crop' => true],
    'cows' => ['width' => 750, 'height' => 150, 'crop' => true],
];  // not localized

I need to $merge = array_merge($array1, $array2); to return an array like this.

array('dogs' => __('Dogs'), 'cats' => __('Cats'), 'ducks', 'cows');

But I'm getting all kinds of weird results.

Try this:

$merge = array_merge($array1, array_keys($array2));

To append the keys of $array2 as new elements of $array1, use array_push() with the spread operator. This way you don't bother handling the elements of the first array; just add the new elements individually. Demo

array_push($array1, ...array_keys($array2));
