With the current patch submitted for this RFC, your example will
return 2, as it will simply ignore the trailing comma at the end of
your call. You can see the more detailed test at github here[1].

[PHP-DEV] Re:[PHP-DEV] [VOTE] Allow a trailing comma in function calls

[CHU Zhaowei]

Hello Sammy,


I'd like to know if a trailing comma would affect the number of args or not. 
for example,
```
function foo(){
  return func_num_args();

}
foo('a','b',);
```
would return 2 or 3?


best regards,
CHU Zhaowei

Subject:  [PHP-DEV] [VOTE] Allow a trailing comma in function calls

 
Hi internalsland!

Seeing that the mandatory two-week discussion period has completed and
there are no open questions, the RFC to allow a trailing comma in
function calls in PHP 7.3 is up for vote.

https://wiki.php.net/rfc/trailing-comma-function-calls

As this is a change to the language syntax, the RFC requires a 2/3
majority to pass. The voting period will last two weeks beginning now
(2017-10-21 18:30 UTC) and ending 2017-11-04 18:30 UTC.

Happy Halloween! :)

Thanks,
