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:

// If it's empty, just f...jetpack'), $domain)); } does not seem to be reachable.

This check looks for unreachable code. It uses sophisticated control flow analysis techniques to find statements which will never be executed.

Unreachable code is most often the result of return, die or exit statements that have been added for debug purposes.

function fx() {
    try {
        doSomething();
        return true;
    }
    catch (\Exception $e) {
        return false;
    }

    return false;
}

In the above example, the last return false will never be executed, because a return statement has already been met in every possible execution path.

Bug introduced by
The variable $domain 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.
