Complex classes like UrlManager often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use UrlManager, and based on these observations, apply Extract Interface, too.

||
| 68 | * is the configuration array for creating a single URL rule. The configuration will |
||
| 69 | * be merged with [[ruleConfig]] first before it is used for creating the rule object. |
||
| 70 | * |
||
| 71 | * A special shortcut format can be used if a rule only specifies [[UrlRule::pattern|pattern]] |
||
| 72 | * and [[UrlRule::route|route]]: `'pattern' => 'route'`. That is, instead of using a configuration |
||
| 73 | * array, one can use the key to represent the pattern and the value the corresponding route. |
||
| 74 | * For example, `'post/<id:\d+>' => 'post/view'`. |
||
| 75 | * |
||
| 76 | * For RESTful routing the mentioned shortcut format also allows you to specify the |
||
| 77 | * [[UrlRule::verb|HTTP verb]] that the rule should apply for. |
||
| 78 | * You can do that by prepending it to the pattern, separated by space. |
||
| 79 | * For example, `'PUT post/<id:\d+>' => 'post/update'`. |
||
| 80 | * You may specify multiple verbs by separating them with comma |
||
| 81 | * like this: `'POST,PUT post/index' => 'post/create'`. |
||
| 82 | * The supported verbs in the shortcut format are: GET, HEAD, POST, PUT, PATCH and DELETE. |
||
| 83 | * Note that [[UrlRule::mode|mode]] will be set to PARSING_ONLY when specifying verb in this way |
||
| 84 | * so you normally would not specify a verb for normal GET request. |
||
| 85 | * |
||
| 86 | * Here is an example configuration for RESTful CRUD controller: |
||
| 87 | * |
||
| 88 | * ```php |
||
