note 34692 added to function.dba-optimize

Note that the internal structure of each DB that needs to access etherogeneous data in a *fast* way it is not necessarily space-optimized. So, if you add-remove-substitute keys with data having different content length, the db continues to grow, wasting space. So, it is necessary, sometimes, to re-pack the db in order to remove unused data from the db itself. But it is important to remind that, even if the file grows, the data remain optimized and - obviously - the access continues to be fast. Further information are available at dba_replace() user-contributed notes. ---- Manual Page -- http://www.php.net/manual/en/function.dba-optimize.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+34692 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+34692&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+34692&report=yes
