PhpStorm 2023.1 Help

Inlay hints

Inlay hints appear in the editor and provide you with additional information about your code to make it easier to read and navigate.

Inlay hints example

Enable or disable inlay hints

  • Open the Settings dialog (Ctrl+Alt+S), go to Editor | Inlay Hints, expand the groups of inlay hints, and clear the checkboxes next to the hints that you want to hide or show.

    Settings | Inlay Hints
  • In the editor, right-click a hint and select whether you want to disable the specific type of hints or all hints in this cagetogy.

Code vision

Code vision hints display in the editor the number of inheritors and usages for a symbol, show who authored it, and mark symbols that are new or contain uncommitted changes.

When you hover over a hint, it turns into a link. By clicking the link you can navigate to usages or implementations of the class or interface as well as open Version Control annotations.

  • Inheritors show the number of descendants of a class (inheritors), interface (implementations), or trait (used by`s). Click the hint to jump to the descendants. If there are several descendants, select the relevant one from the list. Learn more from Go to implementation.

  • Usages show how many times a class or a method is used in your project. Click the hint to jump to the usage or to select the relevant one from the list. Learn more from Search for usages in a project.

  • Code author shows the person who wrote/edited most code lines in a given code element. The hint also indicates if the element is new, modified in the current revision, or has several contributors who considerably committed to it. Click the hint to open the Git annotations in the gutter. Learn more from Locate code author.

In the right-hand pane of the dialog, configure the default position of inlay hints—whether they should be displayed above symbols or to the right of them—and specify the maximum number of inlay hints to be shown in each position.

You can also configure custom positioning for hints of a specific type.

Configure position for inlay hints in the Settings dialog

Parameter names

Show the names of parameters in function and method calls in the editor to get assistance with passing arguments correctly.

For a number of methods and functions, parameter names are not shown by default: such methods and functions are on the default Exclude list. To enable display of the excluded parameter name hints in the editor, or add more excluded methods or functions, click Exclude list and edit the list.

Settings | Inlay Hints


Show the types of parameters and function return types in the editor.

For function return types in call chains, specify the minimum number of different types to show the hints.

By default, this checkbox is selected and PhpStorm shows inferred values for numeric enums in the TypeScript context. Clear the checkbox to hide the inferred values and show only the values of explicitly initialized constants.
