Improve how function signatures are displayed in tooltips

[ZebulanStanphill]

The current tooltips showing function signatures tend to look pretty messy when optional parameters are involved.

I think the square bracket syntax is too noisy, is unnecessary for params with default arguments, and doesn't even make much sense anymore since in PHP 8 you can include optional params like these in any order you please.

Maybe just have a little badge next to the optional params (without a default param) saying optional?

Additionally, I think it would help if functions with lots of parameters had each param on a separate line.

I think the Intelephense extension handles this fairly well:

@ZebulanStanphill Thank you for the feedback!

You are right, this tooltip syntax we have is dated back from PHP 5.

I agree, that the square brackets are unnecessary, and for more than 3 parameters, we should split them into more lines.

We'll do it.

We have prepared pre-release 1.14.10495 with the updates. The tooltips and generated code will look like the following now:

Thank you again for the suggestion!
