The return type of
return $default; (boolean ) is incompatible with the return type documented by URI_Core::segment of type string .
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() {
