Simulate repository subversion externals to git

Question

I develop webprojects using subversion and I want to move to git. I have a lib folder (php files), a js folder (js files) and for each webproject a different directory (eg project1) which has the lib folder and js folder as externals. That way I have one copy of js files and php lib files in my repository. If I change a file in my project folder marked as external the change propagates to all projects and to the library folder. How can I simulate this behaviour on git?

Perhaps you're looking for Git submodules.
