Duplication introduced by
This method seems to be duplicated in your project.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

You can also find more detailed suggestions in the “Code” section of your repository.

Bug introduced by
It seems like morphToMany() must be provided by classes using this trait. How about adding it as abstract method to this trait?

This check looks for methods that are used by a trait but not required by it.

To illustrate, let’s look at the following code example

trait Idable {
    public function equalIds(Idable $other) {
        return $this->getId() === $other->getId();
    }
}

The trait Idable provides a method equalsId that in turn relies on the method getId(). If this method does not exist on a class mixing in this trait, the method will fail.

Adding the getId() as an abstract method to the trait will make sure it is available.

Bug introduced by
Accessing roles on the interface Spatie\Permission\Contracts\Permission suggest that you code against a concrete implementation. How about adding an instanceof check?

If you access a property on an interface, you most likely code against a concrete implementation of the interface.

Available Fixes

  1. Adding an additional type check:

    interface SomeInterface { }
    class SomeClass implements SomeInterface {
        public $a;
    }
    
    function someFunction(SomeInterface $object) {
        if ($object instanceof SomeClass) {
            $a = $object->a;
        }
    }
    
  2. Changing the type hint:

    interface SomeInterface { }
    class SomeClass implements SomeInterface {
        public $a;
    }
    
    function someFunction(SomeClass $object) {
        $a = $object->a;

Bug introduced by
The property permissions 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 introduced by
It seems like load() must be provided by classes using this trait. How about adding it as abstract method to this trait?

This check looks for methods that are used by a trait but not required by it.

To illustrate, let’s look at the following code example

trait Idable {
    public function equalIds(Idable $other) {
        return $this->getId() === $other->getId();
    }
}

The trait Idable provides a method equalsId that in turn relies on the method getId(). If this method does not exist on a class mixing in this trait, the method will fail.

Adding the getId() as an abstract method to the trait will make sure it is available.
