如何在 PHPStorm 中删除这些水平线？

Question

How to remove these horizontal lines in PHPStorm?

I must have searched through the entire Settings window, but I can't seem to find it. Is it even possible to remove them?

Answer 1

Generally speaking there are two kinds of such separators:

1. Actual method separators -- they appear before method/function body. I do not see them on your screenshot so you must have removed them already.

It's controlled by Settings/Preferences | Editor | General | Appearance | Show method separators Settings/Preferences | Editor | General | Appearance | Show method separators Settings/Preferences | Editor | General | Appearance | Show method separators option:

2. Other separators -- before class/namespace/etc. These are visible on your screenshot.

Thing is: you cannot "remove" them in the same way -- only mask them (make invisible). For that:

1. Settings/Preferences
2. Editor | Color Scheme | General
3. Code | Method separator color

Either remove any assigned colors (try this first) or assign the same color as background.
