			0 ignored issues – show Bug introduced 2015-12-30 17:36 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$annotationObject` is correct as `$this->reader->getProper...ectionProperty, $class)` (which targets `Doctrine\Common\Annotati...getPropertyAnnotation()`) seems to always return null. This check looks for function or method calls that always return null and whose return value is assigned to a variable. class A { function getObject() { return null; } } $a = new A(); $object = $a->getObject(); The method `getObject()` can return nothing but null, so it makes no sense to assign that value to a variable. The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. Loading history...

			0 ignored issues – show Best Practice introduced 2016-11-18 22:40 UTC by Report Bug Copy Issue Report The expression `return array(\Ma27\ApiKe...> $lastActionProperty);` seems to be an `array`, but some of its elements' types (`null`) are incompatible with the return type declared by the interface `Ma27\ApiKeyAuthenticatio...ace::getMetadataForUser` of type `ReflectionProperty[]`. If you return a value from a function or method, it should be a sub-type of the type that is given by the parent type f.e. an interface, or abstract method. This is more formally defined by the Lizkov substitution principle, and guarantees that classes that depend on the parent type can use any instance of a child type interchangably. This principle also belongs to the SOLID principles for object oriented design. Let’s take a look at an example: class Author { private $name; public function __construct($name) { $this->name = $name; } public function getName() { return $this->name; } } abstract class Post { public function getAuthor() { return new Author('Johannes'); } } class BlogPost extends Post { public function getAuthor() { return 'Johannes'; } } class ForumPost extends Post { /* ... */ } function my_function(Post $post) { echo strtoupper($post->getAuthor()); } Our function `my_function` expects a `Post` object, and outputs the author of the post. The base class `Post` returns a simple string and outputting a simple string will work just fine. However, the child class `BlogPost` which is a sub-type of `Post` instead decided to return an `object`, and is therefore violating the SOLID principles. If a `BlogPost` were passed to `my_function`, PHP would not complain, but ultimately fail when executing the `strtoupper` call in its body. Loading history...
