 In this example:
 
 - `intelephense` is set as the primary language server.
-- `phpactor` and `phptools` are disabled (note the `!` prefix).
+- `phpactor`, `phptools` and `phpantom` are disabled (note the `!` prefix).
 - `"..."` expands to the rest of the language servers registered for PHP that are not already listed.
 
 The `"..."` entry acts as a wildcard that includes any registered language server you haven't explicitly mentioned. Servers you list by name keep their position, and `"..."` fills in the remaining ones at that point in the list. Servers prefixed with `!` are excluded entirely. This means that if a new language server extension is installed or a new server is registered for a language, `"..."` will automatically include it. If you want full control over which servers are enabled, omit `"..."` — only the servers you list by name will be used.
