		0 ignored issues – show Documentation introduced 2016-05-16 19:19 UTC by Report Bug Copy Issue Report `$args` is of type `array<integer,?>`, but the function expects a `string`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...

		0 ignored issues – show Documentation Bug introduced 2016-03-02 14:58 UTC by Report Bug Copy Issue Report The method `eval` does not exist on `object<PHPDaemon\Clients\Redis\Pool>`? 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...
