Null Cooalescing Operator, Syntax Error

[rfree190]

My server is running PHP 7.2.26. I'm coding in Dreamweaver CC (Ver 19.2.1). I'm using null-coalescing operator on a page, but Dreamweaver is giving me "Syntax Error, Unexpected '?'" as a line error.

My code:

($_SESSION['form_data']['smtpEmailAddress'] ?? "")

It works fine when viewing in a browser. I only get the error in Dreamweaver. Is there a way to get Dreamweaver to accept Null-coalescing Operator? Dreamweaver is currently set to use PHP 7.1. 7.2 is not an option within preferences.

I know I could just ignore the Dreamweaver error, but I do scan my code for errors using the Dreamweaver error indicators. I'd rather fix Dreamweaver than just ignore the error.

I do not know of any way to upgrade code hinting and error reporting to PHP 7.2.  I think you'll need to ignore it and wait for a DW update.   See the 2020 Roadmap below.
