<?php
    public static function clearInterval(string $interval): int
    {
        preg_match('#([0-9]+)#', $interval, $matches);
        return $matches[1] ?? $interval;

The expression return $matches[1] ?? $interval could return the type string which is incompatible with the type-hinted return integer. Consider adding an additional type-check to rule them out.
