Parameter suggestion for custom functions in Visual Studio Code

Question

Is there a way in Visual Studio Code to get IntelliSense to display me the parameters of my custom function within my php file?
It seems to be working with other languages

Answer 1

As of right now this is not possible natively. Even the popular PHP IntelliSense extension does not support this.

Edit: It seems that the PHP IntelliSense extension has now been updated to support Signature help as well:

I have recently discovered an extension called PHP Intelephense which can do exactly this.

You can even utilize Type Declarations and PHP 7 Return Type Declaration to empower it even more:

The best result is when all type declarations are combined with a DocString, which allows you to write descriptions of parameters. I use the PHP DocBlocker extension to write these, but you could use another, or write them manually.
