HTML多输入文件仅发送一个输入

I have this input code in my form :

<input name="photos" type="file"  multiple>

In my controller class that handle the form inputs :-

$photos = Input::file('photos');
        $count = count($photos);

I am using the count() method just to make sure whether the form is sending a multiple files or not. The return of count method is "1" while I've selected 6

Solved by changing the input name, from :-

<input name="photos" type="file"  multiple>

To:

<input name="photos[]" type="file"  multiple>
