			0 ignored issues – show Bug introduced 2018-02-18 22:08 UTC by Report Bug Copy Issue Report It seems like `$cmd` defined by `\yii\helpers\HtmlPurifie...arg(serialize($data))))` on line `82` can also be of type `false` or `null`; however, `Symfony\Component\Process\Process::__construct()` does only seem to accept `string\|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)) { // $x is an array. } If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue. Loading history... Bug introduced 2018-02-18 22:08 UTC by Report Bug Copy Issue Report It seems like `\Yii::getAlias($this->yiiAlias)` targeting `yii\BaseYii::getAlias()` can also be of type `boolean`; however, `Symfony\Component\Process\Process::__construct()` does only seem to accept `null\|string`, maybe add an additional type check? This check looks at variables that are passed out again to other methods. If the outgoing method call has stricter type requirements than the method itself, an issue is raised. An additional type check may prevent trouble. Loading history...
