		0 ignored issues – show Unused Code Comprehensibility introduced 2017-07-10 04:48 UTC by Report Bug Copy Issue Report `67%` of this comment could be valid code. Did you maybe forget this after debugging? Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it. The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production. This check looks for comments that seem to be mostly valid code and reports them. Loading history...

		0 ignored issues – show Bug introduced 2017-07-10 04:48 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `DebugBar\DataCollector\DataCollectorInterface` as the method `getController()` does only exist in the following implementations of said interface: `LeKoala\DebugBar\Collector\SilverStripeCollector`. 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...

An attempt at access to an undefined property has been detected. This may either be a typographical error or the property has been renamed but there are still references to its old name. If you really want to allow access to undefined properties, you can define magic methods to allow access. See the php core documentation on Overloading. Loading history...
