		0 ignored issues – show Documentation introduced 2018-09-06 02:21 UTC by Report Bug Copy Issue Report `false` is of type `boolean`, but the function expects a `object<Egulias\EmailVali...dation\EmailValidation>`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history... Unused Code introduced 2018-09-06 02:21 UTC by Report Bug Copy Issue Report The call to `EmailValidator::isValid()` has too many arguments starting with `true`. This check compares calls to functions or methods with their respective definitions. If the call has more arguments than are defined, it raises an issue. If a function is defined several times with a different number of parameters, the check may pick up the wrong definition and report false positives. One codebase where this has been known to happen is Wordpress. In this case you can add the `@ignore` PhpDoc annotation to the duplicate definition and it will be ignored. Loading history...
