Implment a text format Reminder using time?

[wasabihowdi]

Hey guys,

I'm trying to implement some sort of text format reminder using PHP. Like I would like my program to send me a reminder 5 minute before the deadline. Any good suggestions so I can approach this program?

thanks,

Howdi

You cannot do that with PHP standalone.

What you need is a so called "scheduler", which usually is part of an Operating System. The scheduler triggers the desired programs at a certain time.

In Linux environment you may use "crontab" to start any job at any time you need. This i used for periodically repeating jobs. If you want to start a program once, you may use the "at"-Command instead.

Both (crontab and at) may be used to trigger a PHP Script which generates the Output for your needs. It does not work vice verse to run a PHP Script, which triggers any job at a certain time. You cannot run PHP Scripts endless in a loop (what would be necessary) and you cannot "awake" a PHP by itself - it must be started by a system service (or daemon).
