		0 ignored issues – show Bug introduced 2016-03-09 14:35 UTC by Report Bug Copy Issue Report It seems like `$path` defined by `$this->locator->locate($file)` on line `34` can also be of type `array`; however, `Symfony\Component\Config...Resource::__construct()` does only seem to accept `string`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($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 Best Practice introduced 2016-03-09 14:35 UTC by Report Bug Copy Issue Report The expression `$type` of type `string\|null` is loosely compared to `false`; this is ambiguous if the string can be empty. You might want to explicitly use `=== null` instead. In PHP, under loose comparison (like `==`, or `!=`, or `switch` conditions), values of different types might be equal. For `string` values, the empty string `''` is a special case, in particular the following results might be unexpected: '' == false // true '' == null // true 'ab' == false // false 'ab' == null // false // It is often better to use strict comparison '' === false // false '' === null // false Loading history...
