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:

/**

 * Can be used for validation of nested structures.
19
 *
20
 * For example, we have an inbound request with the following structure:
21
 *
22
 * ```php
23
 * $request = [
24
 *     'author' => [
25
 *         'name' => 'Dmitry',
26
 *         'age' => 18,
27
 *     ],
28
 * ];
29
 * ```
30
 *
31
 * So to make validation we can configure it like this:
32
 *
33
 * ```php
34
 * $rule = new Nested([
35
 *     'author' => new Nested([
36
 *         'name' => [new HasLength(min: 3)],
37
 *         'age' => [new Number(min: 18)],
38
 *     )];
39
 * ]);
40
 * ```
