To revert a commit in PhpStorm, you can follow these steps:
1. Open the Git tool window: Go to View -> Tool Windows -> Version Control (or use the keyboard shortcut Alt + 9).
2. In the Commit tool window, find the commit you want to revert. You can use the "Log" tab to see a list of commits.
3. Right-click on the commit you want to revert and select "Revert".
4. PhpStorm will create a new commit that undoes the changes made in the selected commit. A new commit message dialog will appear.
5. Review and modify the commit message as desired.
6. Click on the "Revert" button to create the new commit that reverts the changes.
7. Finally, push the changes to the remote repository if needed. You can do this by clicking on the "Git Push" button in the top-right corner of the PhpStorm window.
By following these steps, you should be able to revert a commit in PhpStorm and undo the changes made in that commit.
