htmlentities() expects parameter 1 to be string, array given

I'm trying to add a class to a laravel form. The array is being passed as the third argument, as required, but I get the above error.
我正在尝试向 Laravel 表单添加一个类。根据需要，该数组作为第三个参数传递，但出现上述错误。
{{ Form::input('text', $variable->name, array('class' => 'form-control')) }}
If I get rid of the third argument, the form displays as expected (unstyled). I can't see what I'm doing wrong here - can anyone help?
如果我去掉第三个参数，表单会按预期显示（无样式）。我看不出我在这里做错了什么 - 任何人都可以帮忙吗？

I can see from the api that there is another argument expected:
我可以从 api 中看到还有另一个参数：

http://laravel.com/api/source-class-Illuminate.Html.FormBuilder.html#235-246
('text', $name, $value, $options)

Your array needs to be the fourth argument to Form::input()- the third is the 'default' value. See Laravel's FormBuilderclass:
您的数组需要是第四个参数Form::input()- 第三个是“默认”值。参见 Laravel 的FormBuilder类：
public function input($type, $name, $value = null, $options = array())
