			0 ignored issues – show Bug introduced 2016-01-25 17:03 UTC by Report Bug Copy Issue Report It seems like `$filtered` defined by `static::filterBy($collec... $value, $comparisonOp)` on line `247` can also be of type `object`; however, `Arrayy\Arrayy::__construct()` does only seem to accept `array`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($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 Documentation introduced 2016-01-25 17:03 UTC by Report Bug Copy Issue Report `$collection` is of type `object`, but the function expects a `array`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...
