Hi,

I wasn't entirely sure where to post this so I posted here.
I was wondering if it's possible to use Cron Jobs to open a specified page once a week?

If the page resides on your own hosted server would that be a problem? (Logically thinking that would be easiest)
The page can open and then close after a few seconds.

I've searched around a bit and found certain texts saying how to set up a Cron Job, but nothing explaining what you can actually do with them.

If there is no way to accomplish this via Cron Jobs, does anyone know any other way.

Thank You

This is the correct forum for this question.

You might need to elaborate on what you mean by opening a page. What kind of page?

Hi

Just any page

Say i wanted to open http://www.codingforums.com/
or http://www.google.com/about.html

Would that be possible and then for it to close again after a set time period.

That doesn't make any sense. Open it and do what? If this is running on a web host server which it would be and on a Linux server since you said CRON jobs then opening a file does not mean opening it in the sense that you would open it in a web browser.

What is it that you are trying to achieve?

I'll take that as a no then.

What I am trying to achieve is posted above.
(Open/execute a page or a script that opens a page and then closes itself after a set time period)

Say you had a .php script for logging into an ftp and uploading/downloading a text file. Would you be able to automate that process?
If so would it be much harder to open a web page from a server. I know its port 21 & port 80 with two totally different methods.

You can run scripts using CRON jobs for running queries on databases, you can run scripts to perform various different tasks to files etc.

But when you say opening a website for a few seconds and then closing it doesn't make any sense at all.

Maybe the question should be why do you need to open a website for a few seconds and then close it?

Crons run scripts. For instance -

A cron does something like this ::

Run delete.php at 4:30 AM Everyday

And delete.php might empty a table in the datbase or something like that

I managed to figure it out:D

My Cron job is (runs weekly)
lynx -dump http://www.sitename/cron/test.php

Then the php, which i don't fully understand but it works.

<?php
$fp = fopen("http://www.whatever.com/", "r") or die("OPEN");
while (! feof($fp))
{
fread($fp, 1024) or die("READ");
}
fclose($fp) or die("CLOSE");
?>

It leaves the file in my web root so now i just have to set up another to delete that.
