		0 ignored issues – show Bug introduced 2015-11-21 01:12 UTC by Report Bug Copy Issue Report There is no parameter named `$name`. Was it maybe removed? This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function. Consider the following example. The parameter `$italy` is not defined by the method `finale(...)`. /** * @param array $germany * @param array $island * @param array $italy */ function finale($germany, $island) { return "2:1"; } The most likely cause is that the parameter was removed, but the annotation was not.

		0 ignored issues – show Bug introduced 2015-11-21 01:12 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `ValueObjects\ValueObjectInterface` as the method `getName()` does only exist in the following implementations of said interface: `ValueObjects\DateTime\Month`, `ValueObjects\DateTime\TimeZone`, `ValueObjects\DateTime\WeekDay`, `ValueObjects\Enum\Enum`, `ValueObjects\Geography\Address`, `ValueObjects\Geography\Continent`, `ValueObjects\Geography\Country`, `ValueObjects\Geography\CountryCode`, `ValueObjects\Geography\DistanceFormula`, `ValueObjects\Geography\DistanceUnit`, `ValueObjects\Geography\Ellipsoid`, `ValueObjects\Geography\Street`, `ValueObjects\Money\CurrencyCode`, `ValueObjects\Number\RoundingMode`, `ValueObjects\Person\Gender`, `ValueObjects\Web\IPAddressVersion`. Let’s take a look at an example: interface User { /** @return string / public function getPassword(); } class MyUser implements User { public function getPassword() { // return something } public function getDisplayName() { // return some name. } } class AuthSystem { public function authenticate(User $user) { $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName())); // do something. } } In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break. Available Fixes Change the type-hint for the parameter: class AuthSystem { public function authenticate(MyUser $user) { / ... / } } Add an additional type-check: class AuthSystem { public function authenticate(User $user) { if ($user instanceof MyUser) { $this->logger->info(/* ... /); } // or alternatively if ( ! $user instanceof MyUser) { throw new \LogicException( '$user must be an instance of MyUser, ' .'other instances are not supported.' ); } } } Note:* PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case. Add the method to the interface: interface User { /** @return string / public function getPassword(); /* @return string */ public function getDisplayName(); } Loading history...

Comprehensibility Best Practice introduced 2016-04-20 16:03 UTC by Report Bug Copy Issue Report It is recommend to declare an explicit visibility for `jsonSerialize`. Generally, we recommend to declare visibility for all methods in your source code. This has the advantage of clearly communication to other developers, and also yourself, how this method should be consumed. If you are not sure which visibility to choose, it is a good idea to start with the most restrictive visibility, and then raise visibility as needed, i.e. start with `private`, and only raise it to `protected` if a sub-class needs to have access, or `public` if an external class needs access.
