Convert a comma-delimited string into array of integers?

Question

The following code:

$string = "1,2,3"
$ids = explode(',', $string);
var_dump($ids);

Returns the array:

array(3) {
  [0]=>
  string(1) "1"
  [1]=>
  string(1) "2"
  [2]=>
  string(1) "3"
}

I need for the values to be of type int instead of type string. Is there a better way of doing this than looping through the array with foreach and converting each string to int?

Answer 1

You can achieve this by following code,

$integerIDs = array_map('intval', explode(',', $string));
