I think you're looking at the wrong problem.
whatever you had when this log entry was created
[30-Jan-2013 12:20:44] PHP Notice:
shows that the php interpreter was working.
So whatever you had then worked as far as having a configuration that starts php.
What's likely is that the scripts you have aren;t working (properly), but you're not going to fix that in apache configurations of .htaccess files.
