Php 7.1 return types support

[Moghul]

Consider a function like

    public function getProperty() : ?PropertyType {
        return $this->property;
    }

where our $property is a nullable PropertyType variable.

Currently, php-mode 1.19.1 will show an exception for that question mark. Is it possible to change a setting to make that work right or does it need to be implemented within php-mode?

Thank you for suggestion. As you say, the symbol ? does not have its own face.

It is not difficult to write a pattern that colors ? in your quoted code, but I think that there is a slightly annoying problem when considering the consistency of the argument list and so on.
It depends not only on the pattern of php - mode but also on the implementation of Cc Mode.

We welcome if you have an idea to solve this problem.

I know less than nothing about how emacs & its plugins work, and never learned lisp. I'm not the guy to solve your issue, unfortunately.
