Configuring the behavior of parameter hints

Open the Code Completion page (Settings | Editor | General | Code Completion for Windows and Linux or PhpStorm | Preferences | Editor | General | Code Completion for macOS) and configure the following options in the Parameter info section:

1. To have a complete method or function signature shown rather than a list of required types, select the Show full signatures check box.
   Make sure to include the required third-party JavaScript libraries and PHP-related items in the project source path. Otherwise, names of the parameters will not be displayed.
2. To have the list of parameter types for the called method or function shown automatically after a certain delay, select the Auto pop-up (in ms) check box and specify the time period in milliseconds.
