		0 ignored issues – show Bug Best Practice introduced 2016-08-21 01:37 UTC by Report Bug Copy Issue Report The expression `$this->hash` of type `array` is implicitly converted to a boolean; are you sure this is intended? If so, consider using `empty($expr)` instead to make it clear that you intend to check for an array without elements. This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent. Consider making the comparison explicit by using `empty(..)` or `! empty(...)` instead. Loading history...

		0 ignored issues – show Bug introduced 2016-08-21 01:37 UTC by Report Bug Copy Issue Report It seems like `$match` can also be of type `null`; however, `BEAR\Middleware\Module\StreamRenderer::collect()` does only seem to accept `array`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($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.
