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 Comprehensibility Bug introduced 2015-11-21 01:12 UTC by Report Bug Copy Issue Report It seems like you call parent on a different method (`getValue()` instead of `toNative()`). Are you sure this is correct? If so, you might want to change this to `$this->getValue()`. This check looks for a call to a parent method whose name is different than the method from which it is called. Consider the following code: class Daddy { protected function getFirstName() { return "Eidur"; } protected function getSurName() { return "Gudjohnsen"; } } class Son { public function getFirstName() { return parent::getSurname(); } } The `getFirstName()` method in the `Son` calls the wrong method in the parent class.

		0 ignored issues – show Bug introduced 2017-04-18 19:05 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 `toNative()` does only exist in the following implementations of said interface: `ValueObjects\Boolean\BoolLiteral`, `ValueObjects\Boolean\BooleanString`, `ValueObjects\Climate\Celsius`, `ValueObjects\Climate\Fahrenheit`, `ValueObjects\Climate\Kelvin`, `ValueObjects\Climate\RelativeHumidity`, `ValueObjects\Climate\Temperature`, `ValueObjects\DateTime\Hour`, `ValueObjects\DateTime\Minute`, `ValueObjects\DateTime\Month`, `ValueObjects\DateTime\MonthDay`, `ValueObjects\DateTime\Second`, `ValueObjects\DateTime\WeekDay`, `ValueObjects\DateTime\Year`, `ValueObjects\Enum\Enum`, `ValueObjects\Geography\Continent`, `ValueObjects\Geography\CountryCode`, `ValueObjects\Geography\DistanceFormula`, `ValueObjects\Geography\DistanceUnit`, `ValueObjects\Geography\Ellipsoid`, `ValueObjects\Geography\Latitude`, `ValueObjects\Geography\Longitude`, `ValueObjects\Identity\Imei`, `ValueObjects\Identity\MacAddress`, `ValueObjects\Identity\UUID`, `ValueObjects\Money\CurrencyCode`, `ValueObjects\Number\Complex`, `ValueObjects\Number\Integer`, `ValueObjects\Number\Natural`, `ValueObjects\Number\Real`, `ValueObjects\Number\RoundingMode`, `ValueObjects\Person\Age`, `ValueObjects\Person\Gender`, `ValueObjects\StringLiteral\StringLiteral`, `ValueObjects\Web\Domain`, `ValueObjects\Web\EmailAddress`, `ValueObjects\Web\FragmentIdentifier`, `ValueObjects\Web\Hostname`, `ValueObjects\Web\IPAddress`, `ValueObjects\Web\IPAddressVersion`, `ValueObjects\Web\IPv4Address`, `ValueObjects\Web\IPv6Address`, `ValueObjects\Web\NullFragmentIdentifier`, `ValueObjects\Web\NullQueryString`, `ValueObjects\Web\Path`, `ValueObjects\Web\PortNumber`, `ValueObjects\Web\QueryString`, `ValueObjects\Web\SchemeName`. 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...
