How To Trigger an Event at a Certain Time

[AKalair]

Hi guys,

 

It is possible to trigger an event at a certain time in PHP and MYSQL ?

 

For example I have a database of events and as each one occurs I want it to tweet out a message to Twitter

 

So it is possible to do something like:

 

if (time == timeofevent):

 

Send message

 

 

 

Thanks

Hi,

 

Thanks for the reply

 

Is there no way to do this in the language ?

 

How do things like Google Calander pop up alerts for events ?

 

Thanks

PHP isn't a service. It only comes to life when a web server gets a request that needs to be parsed by it.

 

Cron is the periodic scheduler used on Linux.

They run JavaScript script in the browser that periodically polls server for updates.

I would also assume they run some sort of scheduler every minutes or so and check dates & times and send notifications.

For email notifications for sure. For (in-browser) popups not necessarily.
