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...
