Rebasing a local branch from develop

I want to rebase a feature branch from develop. I am using PhpStorm Git integration and I have 2 different develop branches:

refs/remotes/origin/develop
refs/heads/develop

In order to do not mess up things, which one do I have to choose to rebase?

Solution

I don't know the phpstorm interface for Git, but in the command line I'd do the following:

git checkout develop
git pull origin develop -> this fetches the remote version of the develop branch and merges it (or rebases it, depending on your pull strategy) into/onto your local branch. This way the local and the remote versions of develop are the same
git checkout feature-brach
git rebase develop

If there are any conflicts - resolve them. After that you can create a pull request against develop.
