+- **Named argument completion** — when typing inside call parentheses, parameter names are suggested with a trailing `:`.
+- **PHPDoc tag completion** — context-aware suggestions inside `/** … */` blocks.
+- **Variable name completion** — typing `$` suggests variables that are in scope.
+- **Class name completion** — unqualified and partially-qualified class names are completed from the current file
+- **Function completion** — standalone functions are completed
+- **Constant completion** — constants defined via `define()` are offered alongside class names
+- **Deprecated detection** — members, classes, and functions marked with `@deprecated` in their PHPDoc are shown with strikethrough in the completion list
