How to set up a cron job properly?

    I'm looking to set up a cron job to run a PHP Script on my shared server. I'm having a lot of problems though. I have confirmed that the script functions correctly by navigating to the URL in the browser, so the script isn't the problem. I'm on an Apache server running PHP5.2.17, if that makes any difference.

    My hosting provider provides a Cron Management tool, in there there is the option of cron tabs or scheduled application. I have tried linking to the URL in the scheduled application tab but with no luck. In cron tabs i have used the command:
    lynx > /dev/null -dump "http://mysite.ie/cron.php"

    again to no avail. Am i missing something? Do i need to include any extra lines in my script? Is the text before the link to the script correct?

    I'd appreciate any help.

    (echo "source $HOME/.cshrc"; echo "lynx -dump http://mysite.ie/cron.php") | csh 1>/dev/null 2>&1


    Try something like that.

    I've tried adding a new cron job and using that command but the script is still not performing its function.

    Could it be a problem in my script?

    I'll give an overview of what the script does.
    1. It first includes an external php file
    2. it also includes jquery.min.js
    3. it calls a JS function on body load
    4. this function queries a webpage, takes the html of the webpage and inserts it into a file on my server
    5. further functions are called which parse this file and insert it into a db on the server

    No data is being added to the server.

    Like I said, if i navigate to the script via a browser it works fine. Is there any difference between how the script is executed through a cronjob?
