			0 ignored issues – show Coding Style introduced 2016-06-05 14:07 UTC by Report Bug Copy Issue Report It is generally advisable to only define one property per statement. Only declaring a single property per statement allows you to later on add doc comments more easily. It is also recommended by PSR2, so it is a common style that many people expect. Loading history...

			0 ignored issues – show Bug introduced 2016-06-05 14:07 UTC by Report Bug Copy Issue Report It seems like `$this->config` can be `null`; however, `__construct()` does not accept `null`, maybe add an additional type check? Unless you are absolutely sure that the expression can never be null because of other conditions, we strongly recommend to add an additional type check to your code: /** @return stdClass\|null */ function mayReturnNull() { } function doesNotAcceptNull(stdClass $x) { } // With potential error. function withoutCheck() { $x = mayReturnNull(); doesNotAcceptNull($x); // Potential error here. } // Safe - Alternative 1 function withCheck1() { $x = mayReturnNull(); if ( ! $x instanceof stdClass) { throw new \LogicException('$x must be defined.'); } doesNotAcceptNull($x); } // Safe - Alternative 2 function withCheck2() { $x = mayReturnNull(); if ($x instanceof stdClass) { doesNotAcceptNull($x); } } Loading history...
