Flatten 2d array and cast all string values to int

Question

How should I make this array value that is in string form

Array
(
    [0] => ["1","2"]
    [1] => ["5"]
)

into int form

Array
(
    [0] => 1
    [1] => 2
    [2] => 5
)

Is it complicated? Anyone can help?

Answer 1

you can use array_map to parse string to int and array_reduce with array_merge to join the arrays

$data = Array(["1","2"],["5"]);
$result = array_map('intval', array_reduce($data, 'array_merge', array()));
print_r($result);
