explode integers only?

Hi all🙂
If I have the below string how can I only explode only the interger values into an array?
$string="1,2,hi,453,222,bye,,,32,";

explode using comma as separator, iterate over the resulting array and filter out non-numbers.

use a regular expression to filter out all non-numeric characters and then explode it.
