I am having my internship, and i was asked to automate the uploading of file and store the data to MySQL every 8:00am. i've read a lot of articles about crontab/cronjob/php:cron. but i am wondering what is a cron.php and what codes/scripts in that file. i also want to know what is .BAT for. do you have any steps and scripts for my problem? thanks alot.. 

Is it possible to have a cron job merely by php ? not by OS (like linux cron). I mean having a php code to repeat a process on with a timer (e.g. every 5min).
