choose the code style scheme to be used as the base for your custom coding style for the selected language ( Source ).

In other words: after selecting a scheme, you can set different formatting options , like tabs vs spaces, tab size or line breaks etc. To use those settings in your current project, you need to click Manage , select your edited scheme and click Copy to Project . After this, you can press Ctrl + Alt + L ( Code > Reformat Code... ) in the editor to reformat a file according to those scheme settings.

What does it do?

You may be surprised .. but it allows you to choose another (different) Code Style scheme for this project.

PhpStorm supports globally defined schemas (by default it provides only one -- "Default") which can be used by any project and project-specific schema called "Project" which available for this project only (and stored together with other project-specific settings).
