Event Manager Class: - it will be executed automatically with (a timer every minute or 10 seconds). (CAUTION: I don't events to start twice) - It will start events every: 1. Day in a certain hh:mm. EX: 20:00 so at 20:00 it will start. 2. Day of week wd:hh:mm. EX: 06:18:00 it will start on Saturday 18:00 3. Week of month (1st week) and Day of that week (saturday). w:wd:hh:mm (w = first/second/third/fourth week wd=weekday) 4. Day of a month example: 1st of Jan. or 24th of Dec. md:hh:mm (md = month day 0-31) 5. Month of a year and week of the month and day of the week. example: Jun 3rd week Fri. mm:ww:wd:hh:mm (mm = month 12 / ww= week (1/2/3/4) / wd = weekday) - Also it will have a time to end the event and that could be optional. - It will print a sentence : Event has started. inside a method StartEvent() - It will print a sentence when ends: Event has ended. inside a method EndEvent(). (optional if there is an end time or just a time set like 1 hour or 2 hours or so.) - Calculating the time it will end at. example: in the start echo the even will end in x hours. (optional: if there is an end time) - It will print a message every x hour (Next Event is EVENT_X it will start in Saturday May 23 2016). MySQL table example: DROP TABLE IF EXISTS `events`; CREATE TABLE `events` ( `id` int(11) NOT NULL AUTO_INCREMENT, `Event_name` varchar(255) NOT NULL, `Period` set('DAILY','WEEKLY','MONTHLY','ANNUALLY') NOT NULL DEFAULT '', `start_time` varchar(255) NOT NULL, `end_time` varchar(255) DEFAULT NULL, `start_command` varchar(255) NOT NULL, `end_command` varchar(255) DEFAULT NULL, `started` int(1) NOT NULL DEFAULT 0, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; Examples just to give an idea how I want it to work. start_time: Period(MONTHLY) "week:weekday:hh:mm:ss" so it will be like 1:Sat:20:00:00 1 stands for 1st week or the month. Another example: Period(ANUALLY) "month:week:weekday:hh:mm:ss" so it will be like May:1:Sat:20:00:00 1 stands for 1st week or the month.
