What PHP setting will remove this feature?

[MrPNW_]

In the attached image, please see the "IF" statment and it' conditions. Notice the grayed values "password:" and "hash:", which you can't delete because they're not really there. I'm using version 8.3.10 of PHP which I believe is the latest version. How do I remove this feature?

Thanks,
Blake

This is an IDE feature, like Inline Parameters in VSCode or Inlay Hints in PhpStorm
