			0 ignored issues – show Coding Style introduced 2015-12-17 08:53 UTC by Report Bug Copy Issue Report The visibility should be declared for property `$priority`. The PSR-2 coding standard requires that all properties in a class have their visibility explicitly declared. If you declare a property using class A { var $property; } the property is implicitly global. To learn more about the PSR-2, please see the PHP-FIG site on the PSR-2. Loading history...

Coding Style introduced 2015-12-17 08:53 UTC by Report Bug Copy Issue Report `answer` uses the super-global variable `$_SERVER` which is generally not recommended. Instead of super-globals, we recommend to explicitly inject the dependencies of your class. This makes your code less dependent on global state and it becomes generally more testable: // Bad class Router { public function generate($path) { return $_SERVER['HOST'].$path; } } // Better class Router { private $host; public function __construct($host) { $this->host = $host; } public function generate($path) { return $this->host.$path; } } class Controller { public function myAction(Request $request) { // Instead of $page = isset($_GET['page']) ? intval($_GET['page']) : 1; // Better (assuming you use the Symfony2 request) $page = $request->query->get('page', 1); } } Loading history...

			0 ignored issues – show Bug Best Practice introduced 2015-12-17 08:53 UTC by Report Bug Copy Issue Report The return type of `return preg_match(\Jarvi...ed_class()), $command);` (`integer`) is incompatible with the return type declared by the interface `JarvisPHP\Core\JarvisPluginInterface::isLikely` of type `boolean`. 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...
