I was looking at some PHP autoresponder type scripts over at hotscripts.com, and I noticed that most of them say you can send a followup message, say every day/week/month without running Crontabs or without using Cron Jobs. I was wondering, how can they have timed events like that without cron, unless of course the user was supposed to leave their browser open for a month
thx in adavance
Well, none of the free ones do this so you won't be able to view the source. Maybe they do just leave a browser open and a timer on the server?
This one does it http://www.hotscripts.com/Detailed/20965.html
It has a fully functional demo online, if that might hold some clues.
