Code refactoring

1. Select an item to refactor. You can select a file/folder in the Project tool window or expression/symbol in the editor.

2. Press CtrlAltShift0T to open a list of refactorings that can be selected.

   

   Alternatively, you can use a keyboard shortcut for a specific refactoring.

   You can also make a multi-caret selection for an extended range of refactoring operations, including Encapsulate Fields, Move Static Members, Extract Delegate, Extract Interface, and Extract Superclass. To utilize this feature, place a caret in each member you want to apply the refactoring to, and the IDE will automatically preselect and check these members in the refactoring dialog.

If you need to undo your refactoring, press Ctrl0Z.

For some refactorings, PhpStorm lets you preview the changes before applying them. The dialog window for such refactoring actions has the Preview button on it.

1. Click Preview in the dialog to see potential changes (the list of usages where the refactoring will be performed).

   

2. In the Find tool window that opens, check the changes that are going to be made. You can exclude Delete or remove Ctrl0X changes that you consider unnecessary.

   

3. Click Do Refactor to proceed with the changes.

When PhpStorm encounters problems with your refactoring, it opens a dialog with the list of conflicts and their brief descriptions.

• Click Continue to ignore the problem and proceed to open the preview in the Find tool window.

• Click Show Conflicts in View to open the conflict entries in the Find tool window and deal with them further.

  For example, you can try to exclude an entry from refactoring by pressing Delete or click Cancel and return to the editor.

  

1. In the Settings dialog (CtrlAlt0S), select Editor | Code Editing.

2. On the Code Editing page, in the Refactorings section, adjust the refactoring options and click OK.
