Subject: RE: scheduling - the easy way

I don't think the answers so far provided answer the original question. I get the impression that the web server in question is probably at a hosting company and therefore no shell commands could be used to schedule scripts.

Here is an idea for a way of scheduling a script to run on a particular day. While it is not possible to make it happen at a particular time, unless triggering it manually, if your website is getting regular hits, it will run on the right day.

Now what you could do, is have a PHP function attached to your home page that gets either the server or the client date and if the day is a particular number (eg. "$day==01") then your scheduled function runs.

Now I think that you will only want to run them once so pseudo code is like this;

#only way to safely maintain state
$runflag = read from file or database

#get the day from server or client
$day = (date("d"));

if ($runflag == 0 && $day == 01) {
$runflag=1;
write $runflag to file or database
run your functions
} elseif ($day != 01) {
$runflag=0
write $runflag to file or database
}

Now on the first of the month the first person to request your homepage will trigger the functions to fun. $runflag is set, so that any subsequent requests on day '01' do not trigger a re-run of the functions. From day '02' through day '31', 0 is written to a file. So any load of the webpage throughout the month will reset the flag so that the functions can run again on the first of the month.

I haven't tested this but I can't see any reason why it would not work. It lets you schedule scripts without the security issues of SSH.
