			0 ignored issues – show Unused Code introduced 2016-04-06 01:27 UTC by Report Bug Copy Issue Report The call to the method `PHPHtmlParser\Dom\AbstractNode::getParent()` 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).

In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code: class MyClass { } $x = new MyClass(); $x->foo = true; Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion: class MyClass { public $foo; } $x = new MyClass(); $x->foo = true; Loading history...

			0 ignored issues – show Bug Best Practice introduced 2016-03-10 00:55 UTC by Report Bug Copy Issue Report The return type of `return $nodes;` (`PHPHtmlParser\Dom\Collection`) is incompatible with the return type documented by `PHPHtmlParser\Dom\AbstractNode::find` of type `array\|PHPHtmlParser\Dom\AbstractNode`. If you return a value from a function or method, it should be a sub-type of the type that is given by the parent type f.e. an interface, or abstract method. This is more formally defined by the Lizkov substitution principle, and guarantees that classes that depend on the parent type can use any instance of a child type interchangably. This principle also belongs to the SOLID principles for object oriented design. Let’s take a look at an example: class Author { private $name; public function __construct($name) { $this->name = $name; } public function getName() { return $this->name; } } abstract class Post { public function getAuthor() { return 'Johannes'; } } class BlogPost extends Post { public function getAuthor() { return new Author('Johannes'); } } class ForumPost extends Post { /* ... */ } function my_function(Post $post) { echo strtoupper($post->getAuthor()); } Our function `my_function` expects a `Post` object, and outputs the author of the post. The base class `Post` returns a simple string and outputting a simple string will work just fine. However, the child class `BlogPost` which is a sub-type of `Post` instead decided to return an `object`, and is therefore violating the SOLID principles. If a `BlogPost` were passed to `my_function`, PHP would not complain, but ultimately fail when executing the `strtoupper` call in its body. Loading history...
