Creating and Managing Projects
Whatever you do in PhpStorm, you do that in the context of a project. A project is an organizational unit that represents a complete software solution. It serves as a basis for coding assistance, bulk refactoring, coding style consistency, etc.
Once you have opened a folder in PhpStorm, the .idea subfolder is added to it where PhpStorm stores its internal configuration settings, for example, for the project code style or the version control system.
PhpStorm does not support direct editing of files on remote hosts. Therefore to work with remote sources in PhpStorm, you need to download them and arrange them in a PhpStorm project. To keep your local and remote sources synchronized, configure automatic upload using the Upload changed files automatically to the default server drop-down list in the Options dialog box.
A project in PhpStorm is represented in the Directory Based Format. A project directory is marked with icon.
Such project directory contains the .idea directory, with the following files:
*.iml file that describes the project structure.
workspace.xml file that contains your workspace preferences.
A number of xml files. Each xml file is responsible for its own set of settings, that can be recognized by its name: projectCodeStyle.xml, encodings.xml, vcs.xml etc.
Thus, for example, adding a new run/debug configuration and changing encoding will affect two different xml files. This helps avoid merge conflicts when the project settings are stored in a version control system and modified by the different team members.
.idea directory is not visible in the Project view of the Project Tool Window.
