PHP推送值数组从一个到另一个

Question

i have two arrays and want to get one

//first

        [0] => Array (
        [drink] => A
        [litres] => 100.05
        )
    [1] => Array (
        [drink] => B
        [litres] => 3943
        )
    [2] => Array (
        [drink] => C
        [litres] => 1.46
        )


  //second      

        [0] => 22
        [1] => 12
        [2] => 16

The result should be:

[0] => Array (
    [drink] => A
    [litres] => 100.05
    [price] => 22
    )
[1] => Array (
    [drink] => B
    [litres] => 3943
    [price] => 12
    )
[2] => Array (
    [drink] => C
    [litres] => 1.46
    [price] => 16
    )

i tried with loops , merge etc all i should find on this site. But i dont get it.

foreach ($arr as $array2) {
    $array1[] = array( 'price' => $array2 );
}

print_r($array1);

i dont get it

Thanks in advance

Answer 1

$result = array_map(function($i, $j) { return array_merge($i, array('price'=>$j)); }, 
                    $arr1, $arr2);
