In fact PHP5 session also provides a function session_set_cookie_params (); To set the lifetime of the PHP5 session, the function must be called before the session_start () function call:Copy the Code code as follows:$lifeTime = 24 * 3600; Save the daySession_set_cookie_params ($lifeTime);Session_Start ();

Explorer 10 and Windows 8. You can provide badge notifications directly on your pinned site tiles. This means that you do not have to open the site in your browser to see the updates for those sites.For example, use IE10 in Windows 8 Consumer Preview to fix a Fresh Tweet presentation.Tiles for pinned sites are updated periodically and will notify users when a new Tweet appears. Background notifications require the components provided by the site.These components include: (1) badge notification

skill is to force the modification of the session file time to the future time, so that other users will not be able to recycle your session file after triggering gc.
The session must be rewritten with session_set_save_handler.In fact, you set the expiration time for one year, but other users who haven't saved it for one year will trigger the gc of the session and forcibly recycle your session. Rewrite the following two methods:1. store redis, mysql, and other databases. you can control the
Restore accidentally deleted data information:
1. Execute alter table table_name enable row movement;
2. Execute flashback table table_name to timestamp to_timestamp ('2017-05-24 14:59:36 ', 'yyyy-mm-dd hh24: MI: ss ');
Query historical operation data:
A reasonable method is to first find the accidentally deleted data from the flash back area, and then insert the accidentally deleted data into the original table.

After logging on to the system, the system automatically exits after being inactive for 1440 seconds. You have to log on multiple times a day. Finally, you have time to solve this problem.
