sending e-mails periodically???

I have a site and i am sending the statistics to my writers with a single php execution like "send_stats.php" but i don't want to write the url everytime... How can I send these details periodically to my writers???

If you're on a "unix" system, you can set up crontab to execute the script

Is there a way to do this without crontabs???

I agree with Lindset on the crontabs. I have a php script that I use to set and edit crontabs which makes it really easy to manage.

Ok i know the crons but i can not reach the crontabs because of my hosting firm so is there a way to do this with sessions???

well there is a way to do it,....but it is not a good way

You could store the time that the email is supposed to be sent. Then build a script that will check that date/time.
Then include that script on every page as an include.

is there a function like mail_once for ex:

if(date("H")==12) {
mail_once("myname@mysite.com","Hi","the stats","From: I");
}

so i can include it in my index.php
???
