They both seem to do the same thing: return the output buffer content to you and delete it aftewards.

Which one should I use?

ob_get_clean() removes the buffer (without printing it), and returns its content.

ob_get_flush() prints the buffer, removes it, and returns its content.

Both function will terminate the buffer.
