 ### Adding custom validation rules on top
 If the default rules don't satisfy your needs, you can add some more on top:
 ```php
-$rules = array('validateCustom' => array(
-		'rule' => array('custom', '#^[a-z0-9]+$#'), // Just a test example, never use this regex!
+$rules = ['validateCustom' => [
+		'rule' => ['custom', '#^[a-z0-9]+$#'], // Just a test example, never use this regex!
 		'message' => __('Foo Bar'),
 		'last' => true,
-	),
-	'validateCustomExt' => array(
-		'rule' => array('custom', '#^[a-z]+$#'), // Just a test example, never use this regex!
+	],
+	'validateCustomExt' => [
+		'rule' => ['custom', '#^[a-z]+$#'], // Just a test example, never use this regex!
 		'message' => __('Foo Bar Ext'),
 		'last' => true,
-	)
+	]
 );
-$this->User->Behaviors->load('Tools.Passwordable', array(
-	'customValidation' => $rules));
+$this->User->Behaviors->load('Tools.Passwordable', ['customValidation' => $rules]);
 ```
 But please do NOT use the above regex examples. Also never try to limit the chars to only a subset of characters.
 Always allow [a-z], [0-9] and ALL special chars a user can possibly type in.
