How to add a range of elements of an array to another array at a specific position in PHP

Answer 1

$source = [10, 20, 30, 40, 50, 60, 70];
$target = [1, 2, 3, 4];

// Insert elements from index 2 to 4 (30, 40, 50) into $target at position 1
$rangeToInsert = array_slice($source, 2, 3);
array_splice($target, 1, 0, $rangeToInsert);

print_r($target);  



/*
run:

Array
(
    [0] => 1
    [1] => 30
    [2] => 40
    [3] => 50
    [4] => 2
    [5] => 3
