The recommended way to write validation and authorization logic is to put that logic in separate request classes  This way your controller code will remain clean   You can create a request class by executing php artisan make request SomeRequest   In each request class s rules   method define your validation rules     SomeRequest php public function rules        return        name       gt               required              array      input must be an array            min 3      there must be three members in the array             name       gt               required              string        input must be of type string            distinct      members of the array must be unique            min 3         each string must have min 3 chars                In your controller write your route function like this      SomeController php public function store SomeRequest  request          Request is already validated before reaching this point       Your controller logic goes here     public function update SomeRequest  request         It isn t uncommon for the same validation to be required      in multiple places in the same controller  A request class      can be beneficial in this way      Each request class comes with pre- and post-validation hooks methods which can be customized based on business logic and special cases in order to modify the normal behavior of request class   You may create parent request classes for similar types of requests  e g  web and api  requests and then encapsulate some common request logic in these parent classes

Asterisk symbol     is used to check values in the array  not the array itself    validator   Validator  make  request- gt all           names       gt   required array min 3        names       gt   required string distinct min 3         In the example above     names  must be an array with at least 3 elements  values in the  names  array must be distinct  unique  strings  at least 3 characters long      EDIT  Since Laravel 5 5 you can call validate   method directly on Request object like so    data    request- gt validate        name       gt   required array min 3        name       gt   required string distinct min 3
