			0 ignored issues – show Unused Code introduced 2016-07-15 16:34 UTC by Report Bug Copy Issue Report The call to the method `Symplify\PHP7_CodeSniffe...cludeRestrictedSniffs()` seems un-needed as the method has no side-effects. PHP Analyzer performs a side-effects analysis of your code. A side-effect is basically anything that might be visible after the scope of the method is left. Let’s take a look at an example: class User { private $email; public function getEmail() { return $this->email; } public function setEmail($email) { $this->email = $email; } } If we look at the `getEmail()` method, we can see that it has no side-effect. Whether you call this method or not, no future calls to other methods are affected by this. As such code as the following is useless: $user = new User(); $user->getEmail(); // This line could safely be removed as it has no effect. On the hand, if we look at the `setEmail()`, this method _has_ side-effects. In the following case, we could not remove the method call: $user = new User(); $user->setEmail('email@domain'); // This line has a side-effect (it changes an // instance variable).

Did you maybe forget this after debugging? Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it. The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production. This check looks for comments that seem to be mostly valid code and reports them. Loading history...
