Hi,

The special algorithm was necessary because the root keys could be
used in session_register() as global variables, which have certain
naming restrictions. This is no longer necessary since
session_register() has been deprecated.

I wrote a patch a while ago to use php_var_serialize but the
complication emerged of adding a version number to the serialized
string (otherwise migrating existing sessions is awkward). I haven't
had time to work on it but can dig up the latest code if you'd like,
it will be another few weeks until I can pick it up again.

Regards,
