merge two arrays based on array1

Question

Hi, I'm trying to merge two arrays for the values of array1 that are set

Array1 ( [0] => false [1] => 200 )
Array2 ( [0] => true [1] => 80 [2] => 60 [3] => 75 [4] => 50 [5] => 0 [6] => 0 [7] => 30 [8] => 40 )

for instance result array:

Array3 ( [0] => false [1] => 200 [2] => 60 [3] => 75 [4] => 50 [5] => 0 [6] => 0 [7] => 30 [8] => 40 )

what would be an efficient way to handle this.

Thanks

Answer 1

See array_merge

For array1 to override array2, use it like this:

$array3 = array_merge($array2, $array1);

Answer 2

Use the array union operator.

$array3 = $array1 + $array2;
