How to fix   Duplicated Code    Complexity   

Duplicated Code

Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.

Common duplication problems, and corresponding solutions are:

Complex Class

 Tip:   Before tackling complexity, make sure that you eliminate any duplication first. This often can reduce the size of classes significantly.

Complex classes like AnnotatedI18nRouteLoader often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.

Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.

While breaking up the class, it is a good idea to analyze how other classes use AnnotatedI18nRouteLoader, and based on these observations, apply Extract Interface, too.

Bug introduced by
It seems like $annot can also be of type object<Symfony\Component...uting\Annotation\Route>; however, FrankDeJonge\SymfonyI18n...RouteLoader::addRoute() does only seem to accept object<FrankDeJonge\Symf...g\Annotation\I18nRoute>, maybe add an additional type check?

If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check:

/**
 * @return array|string
 */
function returnsDifferentValues($x) {
    if ($x) {
        return 'foo';
    }

    return array();
}

$x = returnsDifferentValues($y);
if (is_array($x)) {
    // $x is an array.
}

If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.
