php and cron

[giangiammy]

I don't know if this is possible, but I need to accomplish an action
at a given hour (what cron does): is it possible to do something like
this having a web hosting service with php support?

any other possibilities to do something like this without having
access to cron facilities?

thanks

Yes, if you are able to set cron jobs on your web server. Save your
script in a PHP file like
#!/usr/bin/php
<?php

// Your code here

?>

and call it directly in your cron tab. Don't forget to make it
executable (chmod +x myscript.php or similar).

If you are not able to set cron jobs on your server, then you might
want to try this site:

....this will only work if you happen to have the CLI PHP in /usr/bin/php and
have permissions to run it. If not, but assuming you have shell access, you
could try accessing a URL using wget or curl.

If you don't have access to cron (or at) you could still write a daemon
process that wakes up at intervals to do its stuff - see sleep().

If the schedule is flexible enough and you just want to do it "once a day"
and the like... and taking for granted you do have a web site... A possible
approach is to launch the script from your site. Let me explain:

1) You put your code in a file

2) You choose a page on your site (or maybe an include file)

3) You get a random number and decided upon it whether the script will be
launched
// Not tested!
if(mt_rand(1, 1000)){
system('nohup /foo/var.php &');
}

You can make additional checks so it won't be executed in less than X
hours.

There are webservices that "visit" a page at specific times. Not really
secure, but it is easy to set up.

Will you post some links of some of the web services that do this?

Thanks,
