All your settings should be kept by default by the Fedora package manager, that is if PHP was installed via up2date or yum or whichever one it is that Fedora uses. Even via a tarball, it'd still probably at least rename the files before replacing them, if it replaced them at all.
[us.php.net...] is the documentation you'd want. It doesn't have a "Migrating Configuration Files" like the 4.x to 5.x upgrade guide, so that's a good indication it doesn't mess with any config files.
