Convert a comma-delimited string into array of integers?

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`?
