Just thought I'd share. It works smoothly going from 4.3.9 provided you do

mv /etc/php.ini /etc/php.ini.v4
mv /etc/php.ini.rpmnew /etc/php.ini

Skip the last two move lines. There's no php.conf.rpmnew. Restart Apache and all is well. If you don't you won't have MySQL libraries loaded.

If the php.ini and php.conf files are unmodified, then they will be replaced automatically. Otherwise it wil put the config files in place as .rpmnew.
