从其他数组php替换数组中的键

I have 2 arrays and want to copy keys from first array to second array and keep values on second array:

Arrays:

Array ( [8] => yellow [9] => violet ) 
Array ( [0] => blue [1] => orange )

Desired output:

Array ( [8] => yellow [9] => violet ) 
Array ( [8] => blue [9] => orange )

Get the keys and combine:

$array2 = array_combine(array_keys($array1), $array2);
