new helpers function 'csrf_form' added

[saaiful]

csrf_form() will return csrf token value wrapped with hidden input.
in php call echo csrf_form(); and in blade {!! csrf_form() !!}

Seems odd to name it csrf_form(), it implies to me it'll return a form element due to the name. Not a bad idea though, it doesn't add a ton of new helpers (which I believe is the cause of a lot of helper PRs being closed) and it's actually useful.

Nothing wrong with using <input type="hidden" name="_token" value="{{ csrf_token() }}">

If you need this sort of thing, use the html/form package:

{!! Form::token() !!}
