Hi.

How do I rename a PHPEd project?

I want to know how to do that too.
and also how to rename a workspace as well.

thanks

Renaming a project is as simple as renaming the <ProjectName>.ppj file.
All other files with the same name but different extension are generated automatically afaik.
Renaming a workspace is the same principle, but there the extension is .ppw

Note that if you have the projects in a workspace, the easiest is to remove them from the workspace first, rename them and then add them again.
