Having Two arrays need to Merge two arrays with matching their keys and rest should be empty. I have tried array_merge()
, array_diff()
, array_fill()
but nothing helped.
Array one
Array
(
[5] => PHM
[4] => ODM
[3] => N
[6] => M9
[10] => RDM9
)
array 2
Array
(
[0] => 01
[1] => 02
[2] => 03
[3] => 04
[4] => 05
[5] => 06
[6] => 07
[7] => 08
[8] => 09
[9] => 10
[10] => 11
[11] => 12
[12] => 13
)
Final Output
Array
(
[0] => null
[1] => null
[2] => null
[3] => N
[4] => ODM
[5] => PHM
[6] => M9
[7] => null
[8] => null
[9] => null
[10] => RDM9
[11] => null
[12] => null
)
Make array with all nulls from the 2nd array and replace by values from the 1st array
$arr2 = array_fill_keys(array_flip($arr2), null);
$new = array_replace($arr2, $arr1);
print_r($new);
