How to convert array elements to integer?

Question

PHP

I have an array:
array(2) {
[0]=>
string(2) "62"
[1]=>
string(2) "63"
}
How to convert all its elements from string to integer?

Answer 1

Why would you need that in a dynamically typed language?
But if you suddenly need something
$array = array_map('intval', $array);

Answer 2

run through the array and do intval($value) or (int)$value, they say that the second one works faster

foreach ($array as &$row) {
    $row = (int)$row;
}
