Rebasing a local branch from develop
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 samegit checkout feature-brach
git rebase develop
If there are any conflicts - resolve them. After that you can create a pull request against develop
