2个数组，想合并成这样的，除了循环还有什么好方法吗？

Answer 1

$a = [
            ['skuid' => 123, 'cmmdtyType' => 1],
            ['skuid' => 345, 'cmmdtyType' => 2]
     ];
$b = [
            ['skuid' => 123, 'price' => 1, 'discountRate' => 2],
            ['skuid' => 345, 'price' => 1, 'discountRate' => 2],
     ];
$c = array_replace_recursive($a, $b);
dd($c);

Answer 2

这个就只能通过循环来做了，两个数组一起遍历

Answer 3

function my_array_merge($array1, $array2) {
    $result = Array();
    foreach($array1 as $key => &$value) {
        $result[$key] = array_merge($value, $array2[$key]);
    }
    return $result;
}
