It doesn't appear that sqlite_close actually closes the db file (or if it does, it doesn't free the lock).  If you open a new db, close it and then try to unlink it (on Windows at least) you get a "Permission Denied" error.
sqlite_close说明void sqlite_close ( resource dbhandle )Closes the given database handle. If the database was persistent, it will be closed and removed from the persistent list.
