Subject: Re: [PHP-DEV] 5.3.8, Why is func_num_args() not working on a Clusure?
From: kassner@gmail.com (Rafael Kassner)

func_num_args() must be called inside the Closure to know the number
of arguments that it received. If you are calling outside, it returns
the number of arguments of your testClosure function. There is no
other way than Reflection to do this.

 And, I think func_num_args() does not receive any parameter.
