PHP在数组中添加数组

Question

I have problem to add array into array. I cannot resolve it.

I have this array $A:

Array
(
    [1001] => Array
            (
                [0] => Array
                    (
                        [name] => 'Joe'
                        [surname] => 'Doe'
                        [age]  => 20
                        [height] => 180
                        [weight] => 80
                     )
            )
)

And I have this array $B:

Array
(
    [height] => 200
    [weight] => 100
)

How to create new array to get this result:

Array
(
    [1001] => Array
            (
                [0] => Array
                    (
                        [name] => 'Joe'
                        [surname] => 'Doe'
                        [height] => 180
                        [weight] => 80
                        [age]  => 20
                     )
            )
    [1001] => Array
            (
                [1] => Array
                    (
                        [name] => 'Joe2'
                        [surname] => 'Doe2'
                        [height] => 200
                        [weight] => 100
                        [age]  => 22
                     )
            )
)

I use this, but the result is not correct:

$array[1001][] = [
            'name'   => 'Joe2',
            'surname'=> 'Doe2',
            $B,
            'age' => 22
        ];

Thank you for answer.

You can use the operator + to merge your arrays:

$array = array(
    1001 => array(
        array(
            'name' => 'Joe',
            'surname' => 'Doe',
            'height' => 180,
            'weight' => 80,
            'age'  => 20
        )
    ),
);

$B = array('height' => 200, 'weight' => 100);

$array[1001][] = [
            'name'   => 'Joe2',
            'surname'=> 'Doe2',
            'age' => 22
        ] + $B;

print_r($array);

Will outputs:

Array
(
    [1001] => Array
        (
            [0] => Array
                (
                    [name] => Joe
                    [surname] => Doe
                    [height] => 180
                    [weight] => 80
                    [age] => 20
                )

            [1] => Array
                (
                    [name] => Joe2
                    [surname] => Doe2
                    [age] => 22
                    [height] => 200
                    [weight] => 100
                )

        )
