Have to agree with Dan... You could easily build any backup/checking
routine into a site that would check/perfoem any functions that need to be
without the need for server side interaction.

ie:
if(time of day is now)
        doThisFunction();

I use this to backup data, remove expired users, etc...

Alternatively, I also use cron to run a PHP file which accomplishes backup,
process management, and other administration tasks... primarily because it
is easier to concentrate on one language,
and spitting out errors in html format is easier IMO.

I do think that cron and other scheduled process are part of the development
process... just shouldn't be part of PHP (or apache for that matter). Cron
does that job just fine on its own and with very little overhead.

I disagree! Cronjobs are not a web development problem. That is something
that should be handled on the server/machine side. PHP is purely designed
to dynamically create web pages. It has other things built into it, but
each one interfaces with the web page somehow. A cronjob doesn't use the
web at all. The web is an interactive thing and the whole purpose of a job
scheduler is to avoid interaction.

Sure a job scheduler is useful, but it is outside the scope and mission of
PHP.
