 You can also limit access to actions on a controller using the static `$allowed_actions` array. This allows you to always allow an action, or restrict it to a specific permission or to call a method that checks if the action is allowed.
 
 For example, the default `Controller::$allowed_actions` is
+
 	private static $allowed_actions = array(
 		'handleAction',
 		'handleIndex',
 	);
+	
 which allows the `handleAction` and `handleIndex` methods to be called via a URL.
 
 To allow any action on your controller to be called you can either leave your `$allowed_actions` array empty or not have one at all. This is the default behaviour, however it is not recommended as it allows anything on your controller to be called via a URL, including view-specific methods.

 The recommended approach is to explicitly state the actions that can be called via a URL. Any action not in the `$allowed_actions` array, excluding the default `index` method, is then unable to be called.
 
 To always allow an action to be called, you can either add the name of the action to the array or add a value of `true` to the array, using the name of the method as its index. For example

 If neither of these are enough to decide if an action should be called, you can have the check use a method. The method must be on the controller class and return true if the action is allowed or false if it isn't. To do this add the action to the array as an index with the value being the name of the method to called preceded by '->'. You are able to pass static arguments to the method in much the same way as you can with extensions. Strings are enclosed in quotes, numeric values are written as numbers and true and false are written as true and false. For example
