Plugin-php: [feature] support difference value for trailing commas

[alexander-akait]

Values:

• none doesn't print any trailing commas.
• php5.0 print trailing commas for array
• php7.2 include all for php7.2 + list and use (grouped namepaces only).
• php7.3 include all for php7.2 + function calls (https://wiki.php.net/rfc/trailing-comma-function-calls).
• all is latest stable PHP release (right now it is php7.2, in near future php7.3).

Somebody know when PHP starts support trailing commas for array ? :smile: But php5.0 looks good for me because minimum supported version is 5.

Feel free to feedback

Sounds great! Prettier for JS has the same option, so I'd say it's a good fit for PHP as well. I don't know since when trailing commas in arrays were supported, but PHP 5 seems fine.

Right now we're supporting none and all. The all setting will add trailing commas in multiline arrays.
