Sending array post with file

[vuquangthinh]

I like this library, but i have a trouble with post data I want: $_POST = [ 'foo' => [ 'bar' => 'tar', ], ];

$_FILES = [ 'file1' => .... ];

I am using yii2, and using httpful to create a restclient. But I got: $_POST = [ 'foo' => 'Array' ]; PS: I've debug with "var_dump" $_POST data. I think encode data string has been got a problem.
