[FX.php List] Timers and things for PHP

[Vincenzo P. Menanno]

This is more of a request to see if there is something out there php  
wise that would be acting like a trigger... so every hour ping some  
site or link and send me an email with some information ... is there  
such a thing that one can use this in their php code... and if so  
what kind of impact would it have on overall performance and such  
things.

THanks

Vince
