			0 ignored issues – show Bug introduced 2016-04-15 12:49 UTC by Report Bug Copy Issue Report It seems like you code against a specific sub-type and not the parent class `Symfony\Component\Validator\Constraint` as the method `getIsoCodesClass()` does only exist in the following sub-classes of `Symfony\Component\Validator\Constraint`: `SLLH\IsoCodesValidator\AbstractConstraint`, `SLLH\IsoCodesValidator\A...oCodesGenericConstraint`, `SLLH\IsoCodesValidator\Constraints\Bban`, `SLLH\IsoCodesValidator\Constraints\Cif`, `SLLH\IsoCodesValidator\Constraints\CreditCard`, `SLLH\IsoCodesValidator\Constraints\Ean13`, `SLLH\IsoCodesValidator\Constraints\Ean8`, `SLLH\IsoCodesValidator\Constraints\Iban`, `SLLH\IsoCodesValidator\Constraints\Insee`, `SLLH\IsoCodesValidator\Constraints\Ip`, `SLLH\IsoCodesValidator\Constraints\Isbn`, `SLLH\IsoCodesValidator\Constraints\Nif`, `SLLH\IsoCodesValidator\Constraints\Siren`, `SLLH\IsoCodesValidator\Constraints\Siret`, `SLLH\IsoCodesValidator\Constraints\Ssn`, `SLLH\IsoCodesValidator\C...StructuredCommunication`, `SLLH\IsoCodesValidator\Constraints\SwiftBic`, `SLLH\IsoCodesValidator\Constraints\Uknin`, `SLLH\IsoCodesValidator\Constraints\Vat`, `SLLH\IsoCodesValidator\Constraints\ZipCode`. Maybe you want to `instanceof` check for one of these explicitly? Let’s take a look at an example: abstract class User { /** @return string / abstract public function getPassword(); } class MyUser extends 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 sub-classes 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 parent class: abstract class User { /** @return string / abstract public function getPassword(); /* @return string */ abstract public function getDisplayName(); } Loading history...

			0 ignored issues – show Documentation introduced 2016-04-15 12:49 UTC by Report Bug Copy Issue Report `$constraint` is of type `object<Symfony\Component\Validator\Constraint>`, but the function expects a `object<SLLH\IsoCodesVali...or\ConstraintInterface>`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...
