Deprecated Code introduced by
The interface Robo\Config\GlobalOptionDefaultValuesInterface has been deprecated with message: Use robo.yml instead robo.yml: options: simulated: false progress-delay: 2 etc.

This class, trait or interface has been deprecated. The supplier of the file has supplied an explanatory message.

The explanatory message should give you some clue as to whether and when the type will be removed from the class and what other constant to use instead.

Bug introduced by
It seems like $data defined by parameter $data on line 21 can also be of type null; however, Robo\Config\Config::import() does only seem to accept array, maybe add an additional type check?

This check looks at variables that have been passed in as parameters and are passed out again to other methods.

If the outgoing method call has stricter type requirements than the method itself, an issue is raised.

An additional type check may prevent trouble.

Bug introduced by
The property defaults does not exist. Did you maybe forget to declare it?

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;

Bug Best Practice introduced by
The return type of return $this->replace($data); (Robo\Config\Config) is incompatible with the return type declared by the interface Consolidation\Config\ConfigInterface::import of type Consolidation\Config\Config.

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.
