			0 ignored issues – show Security Bug introduced 2019-09-03 19:42 UTC by Report Bug Copy Issue Report It seems like `$content` defined by `$response->getContent()` on line `41` can also be of type `false`; however, `Spatie\CookieConsent\Coo...losingBodyTagPosition()` does only seem to accept `string`, did you maybe forget to handle an error condition? This check looks for type mismatches where the missing type is `false`. This is usually indicative of an error condtion. Consider the follow example <?php function getDate($date) { if ($date !== null) { return new DateTime($date); } return false; } This function either returns a new `DateTime` object or false, if there was an error. This is a typical pattern in PHP programming to show that an error has occurred without raising an exception. The calling code should check for this returned `false` before passing on the value to another function or method that may not be able to handle a `false`. Loading history...

It seems like the method you are trying to call exists only in some of the possible types. Let’s take a look at an example: class A { public function foo() { } } class B extends A { public function bar() { } } /** * @param A\|B $x / function someFunction($x) { $x->foo(); // This call is fine as the method exists in A and B. $x->bar(); // This method only exists in B and might cause an error. } Available Fixes Add an additional type-check: /* * @param A\|B $x / function someFunction($x) { $x->foo(); if ($x instanceof B) { $x->bar(); } } Only allow a single type to be passed if the variable comes from a parameter: function someFunction(B $x) { /* ... */ } Loading history...
