How to display PHP function signature?

When typing a PHP function, eg: str_pad(), I would like to get the function signature to display.

The signature displays when typing str_pa[Ctrl+Space] to autocomplete, but not when typing str_pad(
And as soon as the signature dissapears (ie: clicking elsewhere) I'd like to know how to get it back too, is that possible?

You can call the hints for this (ctrl+p) and you'll get the function's parameters and you can also call the documentation (ctrl+q) for further details.

I think there's a feature request in the track for automatically inserting the function's params when you select it from the code completion dropdown, which in my opinion is a time saver.
