Then maybe all $_Post and $_get in project. That could be sooo awesome.

It's possible if it's checking everything in the project, the string between. Just saying. I mean It should be.

I created an extension that does this at https://marketplace.visualstudio.com/items?itemName=ssigwart.php-extra-completions.

@bmewburn, feel free to copy this into your extension if you want. I'll try to remove it from my extension once you support it in your official extension. Also, I know this is closed source, but if you want me to help with anything, I'd be willing to help.
