+
+The `Rule::anyOf` validation rule allows you to specify that the field under validation must satisfy any of the given validation rulesets. For example, the following rule will validate that the `username` field is either an email address or an alpha-numeric string (including dashes) that is at least 6 characters long:
+
+```php
+use Illuminate\Validation\Rule;
+
+'username' => [
+    'required',
+    Rule::anyOf([
+        ['string', 'email'],
+        ['string', 'alpha_dash', 'min:6'],
+    ]),
