Working with source code
PhpStorm automatically saves changes that you make in your files. Saving is triggered by various events, such as compiling, running, debugging, performing version control operations, closing a file or a project, or quitting the IDE entirely. The actual events are predefined and cannot be configured, but you can be sure that changes will not be lost as you work.
Configure autosave behavior
In the Settings/Preferences dialog (Ctrl+Alt+S), expand Appearance and Behavior, and click System Settings.
- Under Synchronization, configure the following options:
Save files on frame deactivation (when you switch to a different application)
- Save files automatically if application is idle for N seconds
Mark files with unsaved changes
In the Settings/Preferences dialog (Ctrl+Alt+S), expand Editor, then expand General, and click Editor Tabs.
Select the Mark modified tabs with asterisk checkbox.
