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.

18
 * User is the class for the `user` application component that manages the user authentication status.
19
 *
20
 * You may use [[isGuest]] to determine whether the current user is a guest or not.
21
 * If the user is a guest, the [[identity]] property would return `null`. Otherwise, it would
22
 * be an instance of [[IdentityInterface]].
23
 *
24
 * You may call various methods to change the user authentication status:
25
 *
26
 * - [[login()]]: sets the specified identity and remembers the authentication status in session and cookie;
27
 * - [[logout()]]: marks the user as a guest and clears the relevant information from session and cookie;
28
 * - [[setIdentity()]]: changes the user identity without touching session or cookie
29
 *   (this is best used in stateless RESTful API implementation).
30
 *
31
 * Note that User only maintains the user authentication status. It does NOT handle how to authenticate
32
 * a user. The logic of how to authenticate a user should be done in the class implementing [[IdentityInterface]].
33
 * You are also required to set [[identityClass]] with the name of this class.
34
 *
35
 * User is configured as an application component in [[\yii\web\Application]] by default.
36
 * You can access that instance via `Yii::$app->user`.
37
 *
38
 * You can modify its configuration by adding an array to your application config under `components`
39
 * as it is shown in the following example:
40
 *
41
 * ```php
42
 * 'user' => [
43
 *     'identityClass' => 'app\models\User', // User must implement the IdentityInterface
44
 *     'enableAutoLogin' => true,
45
 *     // 'loginUrl' => ['user/login'],
46
 *     // ...
47
 * ]
48
 * ```
49
 *
50
 * @property-read string|int|null $id The unique identifier for the user. If `null`, it means the user is a
51
 * guest.
52
 * @property IdentityInterface|null $identity The identity object associated with the currently logged-in
53
 * user. `null` is returned if the user is not logged in (not authenticated).
54
 * @property-read bool $isGuest Whether the current user is a guest.
55
 * @property string $returnUrl The URL that the user should be redirected to after login. Note that the type
56
 * of this property differs in getter and setter. See [[getReturnUrl()]] and [[setReturnUrl()]] for details.

Bug Best Practice introduced by
The expression $identity->validateAuthKey($authKey) of type boolean|null is loosely compared to false; this is ambiguous if the boolean can be false. You might want to explicitly use !== null instead.

If an expression can have both false, and null as possible values. It is generally a good practice to always use strict comparison to clearly distinguish between those two values.

$a = canBeFalseAndNull();

if ( ! $a) { }

Bug Best Practice introduced by
The expression $identity->validateAuthKey($authKey) of type boolean|null is loosely compared to false; this is ambiguous if the boolean can be false. You might want to explicitly use !== null instead.

If an expression can have both false, and null as possible values. It is generally a good practice to always use strict comparison to clearly distinguish between those two values.

$a = canBeFalseAndNull();

// Instead of
if ( ! $a) { }

// Better use one of the explicit versions:
if ($a !== null) { }
if ($a !== false) { }
if ($a !== null && $a !== false) { }
