How do I run an on-page cron job?

Currently all my cron jobs are done though the cron job scheduler. I'd like to somehow be independent of that. I saw a thread on stackoverflow, but I am still not sure how to implement it to this or that particular page:

http://stackoverflow.com/questions/...url-address-every-5-minutes/20267276#20267276

Do I simply place a line similar to this into a php page?

*/5 * * * * curl --request GET 'http://exemple.com/path/check.php?param1=1&param2=2'

Code (markup):

Need some clarification.

 

And that's precisely what I need, a script that would "visit" or "reload" a page internally ever so often so that the DP would get updated. Sounds simple enough, but I spent a couple hours today searching for that script and ended up with nothing.

 

I am using easycron.com for my cron jobs. You can tried using this url: exemple.com/path/check.php?param1=1&param2=2
.

 

I ain't paying for something that should be free. I just want to repeat myself, I need a script that I can place into the pages to run cron jobs independent of any cron job scheduler(s). Hostgator allows me to schedule all kinds of cron jobs and I am happy with that, no need for another service. A script is what I need (if it even exists). Thanks for the tip though.
