Laravel5 $validatorとエラー

自分用にメモ

controller

      $validator = $this->validator($request->all(), $validationArray);
      if ($validator->fails()) {
        dd(
          '1)$validator:',$validator
        , '2)$validator->errors():',$validator->errors() //よく使う。
        , '3)$validator->errors()->all():',$validator->errors()->all() //配列になる。あんまり使えない？
        , '4)$validator->errors()->first("number"):',$validator->errors()->first('number') //viewにエラーメッセージ出す用
        , '5)$validator->messages():',$validator->messages() 
        );
      }

結果
