/**
16
 * UrlRule is provided to simplify the creation of URL rules for RESTful API support.
17
 *
18
 * The simplest usage of UrlRule is to declare a rule like the following in the application configuration,
19
 *
20
 * ```php
21
 * [
22
 *     'class' => 'yii\rest\UrlRule',
23
 *     'controller' => 'user',
24
 * ]
25
 * ```
26
 *
27
 * The above code will create a whole set of URL rules supporting the following RESTful API endpoints:
28
 *
29
 * - `'PUT,PATCH users/<id>' => 'user/update'`: update a user
30
 * - `'DELETE users/<id>' => 'user/delete'`: delete a user
31
 * - `'GET,HEAD users/<id>' => 'user/view'`: return the details/overview/options of a user
32
 * - `'POST users' => 'user/create'`: create a new user
33
 * - `'GET,HEAD users' => 'user/index'`: return a list/overview/options of users
34
 * - `'users/<id>' => 'user/options'`: process all unhandled verbs of a user
35
 * - `'users' => 'user/options'`: process all unhandled verbs of user collection
36
 *
37
 * You may configure [[only]] and/or [[except]] to disable some of the above rules.
38
 * You may configure [[patterns]] to completely redefine your own list of rules.
39
 * You may configure [[controller]] with multiple controller IDs to generate rules for all these controllers.
40
 * For example, the following code will disable the `delete` rule and generate rules for both `user` and `post` controllers:
41
 *
42
 * ```php
43
 * [
44
 *     'class' => 'yii\rest\UrlRule',
45
 *     'controller' => ['user', 'post'],
46
 *     'except' => ['delete'],
47
 * ]
48
 * ```
49
 *
50
 * The property [[controller]] is required and should represent one or multiple controller IDs.
51
 * Each controller ID should be prefixed with the module ID if the controller is within a module.
52
 * The controller ID used in the pattern will be automatically pluralized (e.g. `user` becomes `users`
53
 * as shown in the above examples).
54
 *
55
 * For more details and usage information on UrlRule, see the [guide article on rest routing](guide:rest-routing).

Bug introduced by
The expression $this->controller of type string|array is not guaranteed to be traversable. How about adding an additional type check?

There are different options of fixing this problem.

  1. If you want to be on the safe side, you can add an additional type-check:

    $collection = json_decode($data, true);
    if ( ! is_array($collection)) {
        throw new \RuntimeException('$collection must be an array.');
    }
    
    foreach ($collection as $item) { /** ... */ }
    
  2. If you are sure that the expression is traversable, you might want to add a doc comment cast to improve IDE auto-completion and static analysis:

    /** @var array $collection */
    $collection = json_decode($data, true);
    
    foreach ($collection as $item) { /** .. */ }
    
  3. Mark the issue as a false-positive: Just hover the remove button, in the top-right corner of this issue for more options.
