Adding code to application's core files will get overwritten each time we export the project, right?
yes, but you can exempt a specific project file from being overwritten in Project Settings on the left panel by unchecking them. Note that if you do this, PHPRad assumes you what ever changes that need to be made to that page will be made by you.
