Simple PHP Class

Event Manager Class: - it will be executed automatically with (cron job every 1 second). (CAUTION: I don't events to start twice) - It can run every: 1. Day in a certain hh:mm. 2. Day of week Sat,Fri. 3. Week of month (1st week) and Day of that week (saturday). 4. Day of a month example: 1st of Jan. or 24th of Dec. 5. Month of a year and week of the month and day of the week. example: Jun 3rd week Fri. - Also it will have a time to end the event and that could be optional. - It will echo a sentence : Event has started. inside a method StartEvent() - It will echo a sentence when ended: Event has ended. inside a method EndEvent(). (optional if there is an end time) - 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) - At event start: It will echo a message every x hour (Next Event is 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. example how to run the class: $e = new EventManager; $e->run(); // or $e->check(); Deadline: 2days. Must start working on the project immediately!
