Using CRON jobs to visit url?
I have a web application that has to perform a repeated tasks, Sending messages and alerts, I, already, use a script page do those tasks when it loaded in the browser i.e http://example.com/tasks.php and I included it by the mean of iframe in every page of my web application.
Now I want to change this to use CRON jobs because the first approach may leads to jam performance, So How could I make a CRON job that visits http://example.com/tasks.php. However, I don't want this CRON job creating output files such as day.*!
I host the application on shared hosting service that permits CRON jobs via cPanel.
