Question

Im new to this.I have a cron file called xml.php and i want to run this file at a particular interval.This interval is set by admin on admin panel page.This interval will be stored in the database and i want to fetch that data from db.According to that the xml.php should run.If anybody know how to do this please help.Thanks in advance

Answer 1

Create a script that checks the DB for the last run of the file and the current time difference. If the interval is correct then run the xml script if not then exit. Use cron to run the new script every minute (so every minute it will check if the script needs to be run and run it only if it's time).
