通过键比较将数组值附加到另一个数组

Question

I've this two arrays:

$arr1['someKey'] = [1,2,3,4,5];
$arr2['someKey'] = [6,7];

how do I add|append the values from the second one into the first one by comparing it's keys? The result should be something like:

$arr3['someKey'] = [1,2,3,4,5,6,7];

Any help?

Answer 1

Try array_merge_recursive:

$arr1 = array(
    'someKey' => [1,2,3,4,5],
);
$arr2 = array(
    'someKey' => [6,7],
);

$merged = array_merge_recursive($arr1, $arr2);
