		0 ignored issues – show Bug introduced 2016-05-02 01:49 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `Groundskeeper\Tokens\Token` as the method `getName()` does only exist in the following implementations of said interface: `Groundskeeper\Tokens\Element`, `Groundskeeper\Tokens\ElementTypes\ClosedElement`, `Groundskeeper\Tokens\ElementTypes\OpenElement`, `Groundskeeper\Tokens\Elements\Article`, `Groundskeeper\Tokens\Elements\Aside`, `Groundskeeper\Tokens\Elements\Base`, `Groundskeeper\Tokens\Elements\Body`, `Groundskeeper\Tokens\Elements\Br`, `Groundskeeper\Tokens\Elements\Footer`, `Groundskeeper\Tokens\Elements\H1`, `Groundskeeper\Tokens\Elements\H2`, `Groundskeeper\Tokens\Elements\H3`, `Groundskeeper\Tokens\Elements\H4`, `Groundskeeper\Tokens\Elements\H5`, `Groundskeeper\Tokens\Elements\H6`, `Groundskeeper\Tokens\Elements\Head`, `Groundskeeper\Tokens\Elements\Header`, `Groundskeeper\Tokens\Elements\Hgroup`, `Groundskeeper\Tokens\Elements\Hr`, `Groundskeeper\Tokens\Elements\Html`, `Groundskeeper\Tokens\Elements\Link`, `Groundskeeper\Tokens\Elements\Main`, `Groundskeeper\Tokens\Elements\Meta`, `Groundskeeper\Tokens\Elements\Nav`, `Groundskeeper\Tokens\Elements\Noscript`, `Groundskeeper\Tokens\Elements\Script`, `Groundskeeper\Tokens\Elements\Section`, `Groundskeeper\Tokens\Elements\Style`, `Groundskeeper\Tokens\Elements\Template`, `Groundskeeper\Tokens\Elements\Title`. 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...
