The installation process of JetBrains PhpStorm is very simple and within a short interval of time you will be able to edit the source codes. When you will open the application for first time you need to create a new project or open a project that is already existed. Then you need to navigate the project section which is located on the left side of the main window. You need to right click it in order to open a new file. Once all this is done a new tab will open where you can write your own scripts and then compile it for checking if there exist any errors.
Advanced tools can also be accessed from the bottom of the main window which will allow you to see the project from different perspective. JetBrains PhpStorm is a cross platform application and you can utilize this application on Windows, Mac and Linux operating systems.
