If non-www with index.php redirects to www with index.php then that's part of the problem.

The first rule should redirect any request with index.php to www without it.

A later rule should redirect all non-www to www, but this rule will never be activated for requests with index.php within, because the earlier rule will already have taken care of all problems (the index.php and the www).
