How to concatenate elements in an array correctly?

Question

PHP

There is an array

$arr = [
    'color' => [ 'red', 'blue' ],
    'size' => [ 23, 55 ],
    'price' => [ 100, 200 ]
]

How can I collect a new array by values ​​so that the result is as follows

[
    [ 'red', 23, 100 ],
    [ 'blue', 55, 200 ]
]

I do through one place, as it seems to me. So

$newArr = [];
for ($i = 0; $i < count($arr['color']; $i++) {
    array_push($newArr, [ $arr['color'][$i], $arr['size'][$i], $arr['price'][$i] ] );
}

<?php
$a = [1, 2, 3, 4, 5];
$b = ['one', 'two', 'three', 'four', 'five'];
$c = ['uno', 'dos', 'tres', 'cuatro', 'cinco'];

$d = array_map(null, $a, $b, $c);
print_r($d);
?>
