[PEPr] Comment on Database::Database_SQL_Intervals

Did you look at the Tree PEAR package ? Granted, it's old and need cleaning... but it seems to do the same thing as yours: http://pear.php.net/package/Tree/docs/0.3.4/Tree/Tree_Memory_DBnested.html (see add(), move(), remove() methods) As it's unmaintained, it would make sense to give it a look and improve it, that would be very helpful. -- http://pear.php.net/pepr/pepr-proposal-show.php?id=609
