How to fix   Long Method    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:

Use of global functionality is not recommended; it makes your code harder to test, and less reusable.

Instead of relying on global state, we recommend one of these alternatives:

1. Pass all data via parameters

function myFunction($a, $b) {
    // Do something
}

2. Create a class that maintains your state

class MyClass {
    private $a;
    private $b;

    public function __construct($a, $b) {
        $this->a = $a;
        $this->b = $b;

Bug introduced by
The method repoExists() does not exist on DataObject. Did you maybe mean exists()?

This check marks calls to methods that do not seem to exist on an object.

This is most likely the result of a method being renamed without all references to it being renamed likewise.
