<?php
    public static function buildLink(HasLinks $model, string $routePart, Router $router)
    {
        $routeStub = $model->getRouteName();

        if ($routeStub === null) {

The expression $model->getKeyName() of type string|null is loosely compared to false; this is ambiguous if the string can be empty. You might want to explicitly use === null instead.

            return false;
        }

        // Make the route name, and check if it exists.
        $routeName = "$routeStub.$routePart";

            return strtolower($str);
        });

        // If there's only 1, return just that, otherwise, return an array.
