		0 ignored issues – show Compatibility introduced 2016-02-15 22:10 UTC by Report Bug Copy Issue Report `$part` of type `object<JDR\Mailer\Part\EmailPart>` is not a sub-type of `object<JDR\Mailer\Part\Message>`. It seems like you assume a concrete implementation of the interface `JDR\Mailer\Part\EmailPart` to be always present. This check looks for parameters that are defined as one type in their type hint or doc comment but seem to be used as a narrower type, i.e an implementation of an interface or a subclass. Consider changing the type of the parameter or doing an instanceof check before assuming your parameter is of the expected type. Loading history...

		0 ignored issues – show Bug introduced 2016-02-15 22:10 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `JDR\Mailer\Part\EmailPart` as the method `getContentType()` does only exist in the following implementations of said interface: `JDR\Mailer\Part\Message`, `JDR\Mailer\Part\Template`. 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...
