		0 ignored issues – show Bug introduced 2017-04-12 11:01 UTC by Report Bug Copy Issue Report It seems like `$this->config` can also be of type `array`; however, `FastD\Model\Database::__construct()` does only seem to accept `null`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($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 Bug introduced 2017-04-12 11:01 UTC by Report Bug Copy Issue Report The property `pdo` does not exist. Did you maybe forget to declare it? In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code: class MyClass { } $x = new MyClass(); $x->foo = true; Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion: class MyClass { public $foo; } $x = new MyClass(); $x->foo = true; Loading history...
