Hover popup of... Variable variable?

Like... what?

Is it talking about this?

It's already disabled.

So... how is this useful, why is popping up when it's disabled, and how am I supposed to stop this pop-up that got in the way of my mouse click?

Could you please share a code snippet to reproduce the warning?

Can someone who knows what this pop-up means please explain it? I shouldn't have to post proprietary confidential code or make my own example for this "feature" to get some sort of explanation.

Alright, I didn't realize it was referring to this kind of thing: `$$whatever`

But in my case it shouldn't have applied anyway, because `$result` is not a variable variable.

Also, either I'm not aware of how to disable that particular pop-up warning, or disabling it doesn't work...

Which is it?

Neither are we. It's not an inspection hit, it's not quick documentation popup or anything else, just a popup.

If it's annoying, please submit a usability problem: https://youtrack.jetbrains.com/newIssue?project=WI

Also, if this popup still appears if you copy this file to a new project, please share the file there too - if we don't disable the popup, maybe we fix the bug.

"Neither are we. It's not an inspection hit, it's not quick documentation popup or anything else, just a popup."

Are you on the PHPStorm development team? I honestly don't know if your JB logo on your user avatar (which is generic for some reason) indicates you're a PHPStorm developer or not. I'm not sure what you mean by "we"; everyone on this board? I don't think you can speak for everyone's awareness here unless you're on the coding team and know that what I'm asking for (disable that particular pop-up warning) doesn't exist, even though the setting appears to exist but disabling it doesn't change anything.

Also I'm not sure what you mean "just a popup"... what does that mean in the context of what the editor does? There's all kinds of pop-ups in the editor, like tooltips on buttons, hover pop-ups in code, typing pop-ups... the pop-up I'm talking about is not some generic general pop-up not tied to something specific, it's tied to that particular instance of PHP code, and a particular setting in PHPStorm, as I indicated with screenshots.

Dmitry mentioned it's not documented properly and is a part of inspections. I can submit a usability problem, but please don't speak for the group ("we") unless you can qualify how you know for sure.

Also again I can't paste proprietary business files like our source code. Sorry. I could try to make an example, but that depends on the kind of time I want to spend on it.
