		0 ignored issues – show Bug introduced 2017-05-22 03:25 UTC by Report Bug Copy Issue Report It seems like `$vndError` defined by `$this->reader->getMethod...tation\VndError::class)` on line `33` can also be of type `object`; however, `Ray\WebFormModule\VndErrorHandler::makeVndError()` does only seem to accept `null\|object<Ray\WebFormM...le\Annotation\VndError>`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($x) { if ($x) { return 'foo'; } return array(); } $x = returnsDifferentValues($y); if (is_array($x)) { // $x is an array. } If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.

		0 ignored issues – show Coding Style introduced 2017-12-08 05:49 UTC by Report Bug Copy Issue Report `makeVndError` 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...
