		0 ignored issues – show Unused Code introduced 2016-09-19 03:36 UTC by Report Bug Copy Issue Report The call to the method `WebStream\IO\Reader\InputStreamReader::skip()` 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).
