		0 ignored issues – show Documentation Bug introduced 2016-07-31 23:29 UTC by Report Bug Copy Issue Report The method `getObject` does not exist on `object<DNDeploymentDispatcher>`? Since you implemented `__call`, maybe consider adding a @method annotation. If you implement `__call` and you know which methods are available, you can improve IDE auto-completion and static analysis by adding a @method annotation to the class. This is often the case, when `__call` is implemented by a parent class and only the child class knows which methods exist: class ParentClass { private $data = array(); public function __call($method, array $args) { if (0 === strpos($method, 'get')) { return $this->data[strtolower(substr($method, 3))]; } throw new \LogicException(sprintf('Unsupported method: %s', $method)); } } /** * If this class knows which fields exist, you can specify the methods here: * * @method string getName() */ class SomeClass extends ParentClass { } Loading history...

This check looks for variable assignements that are either overwritten by other assignments or where the variable is not used subsequently. $myVar = 'Value'; $higher = false; if (rand(1, 6) > 3) { $higher = true; } else { $higher = false; } Both the `$myVar` assignment in line 1 and the `$higher` assignment in line 2 are dead. The first because `$myVar` is never used and the second because `$higher` is always overwritten for every possible time line. Loading history...
