How to fix   Complexity   

Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.

For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.

Commonly applied refactorings include:

Bug introduced by
It seems like setRawAttributes() 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.

Coding Style Comprehensibility introduced by
$properties was never initialized. Although not strictly required by PHP, it is generally a good practice to add $properties = array(); before regardless.

Adding an explicit array definition is generally preferable to implicit array definition as it guarantees a stable state of the code.

Let’s take a look at an example:

foreach ($collection as $item) {
    $myArray['foo'] = $item->getFoo();

    if ($item->hasBar()) {
        $myArray['bar'] = $item->getBar();
    }

    // do something with $myArray
}

As you can see in this example, the array $myArray is initialized the first time when the foreach loop is entered. You can also see that the value of the bar key is only written conditionally; thus, its value might result from a previous iteration.

This might or might not be intended. To make your intention clear, your code more readible and to avoid accidental bugs, we recommend to add an explicit initialization $myArray = array() either outside or inside the foreach loop.

Bug introduced by
The property exists 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
The variable $relatedModelName seems only to be defined at a later point. Did you maybe move this code here without moving the variable definition?

This error can happen if you refactor code and forget to move the variable initialization.

Let’s take a look at a simple example:

function someFunction() {
    $x = 5;
    echo $x;
}

The above code is perfectly fine. Now imagine that we re-order the statements:

function someFunction() {
    echo $x;
    $x = 5;
}

In that case, $x would be read before it is initialized. This was a very basic example, however the principle is the same for the found issue.
