			0 ignored issues – show Bug introduced 2015-12-01 18:39 UTC by Report Bug Copy Issue Report It seems like you code against a specific sub-type and not the parent class `Billow\Actions\Action` as the method `getBody()` does only exist in the following sub-classes of `Billow\Actions\Action`: `Billow\Actions\ChangeKernel`, `Billow\Actions\CreateSnapshot`, `Billow\Actions\DisableBackups`, `Billow\Actions\EnableBackups`, `Billow\Actions\EnableIPv6`, `Billow\Actions\EnablePrivateNetworking`, `Billow\Actions\PasswordReset`, `Billow\Actions\PowerCycle`, `Billow\Actions\PowerOff`, `Billow\Actions\PowerOn`, `Billow\Actions\Reboot`, `Billow\Actions\Rebuild`, `Billow\Actions\Rename`, `Billow\Actions\Resize`, `Billow\Actions\Restore`, `Billow\Actions\ShutDown`, `Billow\Actions\Upgrade`. 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 Bug Best Practice introduced 2018-08-03 15:15 UTC by Report Bug Copy Issue Report The return type of `return new \GuzzleHttp\P...oint, $headers, $body);` (`GuzzleHttp\Psr7\Request`) is incompatible with the return type declared by the interface `Billow\Actions\ActionInterface::getRequest` of type `GuzzleHttp\Message\Request`. If you return a value from a function or method, it should be a sub-type of the type that is given by the parent type f.e. an interface, or abstract method. This is more formally defined by the Lizkov substitution principle, and guarantees that classes that depend on the parent type can use any instance of a child type interchangably. This principle also belongs to the SOLID principles for object oriented design. Let’s take a look at an example: class Author { private $name; public function __construct($name) { $this->name = $name; } public function getName() { return $this->name; } } abstract class Post { public function getAuthor() { return 'Johannes'; } } class BlogPost extends Post { public function getAuthor() { return new Author('Johannes'); } } class ForumPost extends Post { /* ... */ } function my_function(Post $post) { echo strtoupper($post->getAuthor()); } Our function `my_function` expects a `Post` object, and outputs the author of the post. The base class `Post` returns a simple string and outputting a simple string will work just fine. However, the child class `BlogPost` which is a sub-type of `Post` instead decided to return an `object`, and is therefore violating the SOLID principles. If a `BlogPost` were passed to `my_function`, PHP would not complain, but ultimately fail when executing the `strtoupper` call in its body. Loading history...
