		0 ignored issues – show Documentation introduced 2017-03-23 20:04 UTC by Report Bug Copy Issue Report The property `$object` is declared protected in `Spaark\CompositeUtils\Model\Generic\GenericContext`. Since you implemented `__get()`, maybe consider adding a @property or @property-read annotation. This makes it easier for IDEs to provide auto-completion. Since your code implements the magic setter `_set`, this function will be called for any write access on an undefined variable. You can add the `@property` annotation to your class or interface to document the existence of this variable. <?php /** * @property int $x * @property int $y * @property string $text */ class MyLabel { private $properties; private $allowedProperties = array('x', 'y', 'text'); public function __get($name) { if (isset($properties[$name]) && in_array($name, $this->allowedProperties)) { return $properties[$name]; } else { return null; } } public function __set($name, $value) { if (in_array($name, $this->allowedProperties)) { $properties[$name] = $value; } else { throw new \LogicException("Property $name is not defined."); } } } Since the property has write access only, you can use the @property-write annotation instead. Of course, you may also just have mistyped another name, in which case you should fix the error. See also the PhpDoc documentation for @property. Loading history...
