数组合并的问题提

Question

Array( [0] => Array ( [skuid] => 121307256 [cmmdtyType] => 1 ) [1] => Array ( [skuid] => 121347694 [cmmdtyType] => 1 ) )，Array( [0] => Array ( [skuId] => 121307256 [price] => 103.10 [discountRate] => ) [1] => Array ( [skuId] => 121347694 [price] => 2.00 [discountRate] => ) )2个数组，想合并成这样的，除了循环还有什么好方法吗？Array( [0] => Array ( [skuid] => 121307256 [cmmdtyType] => 1 [price] => 103.10 [discountRate] => ) [1] => Array ( [skuid] => 121347694 [cmmdtyType] => 1 [price] => 2.00 [discountRate] => ) )

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;
}
