Woah, no one I know has ever paid a publishing fee. Where are you publishing? Anywhere that asks for money is a scam journal. Also, a PhD is fully funded by nature, so all fees for anything should come from your program.
Most well regarded journals in STEM require a publishing fee. That is not the case for the humanities and I believe social sciences, which are always free.
