run automated functions on website

[ukfusion]

Hi Sorry if i'm not posting in the right category.

I have a function on my website which I need to run twice a week....on 2 specific days.

i need this to run without any interaction...n o button presses etc and without the website being viewed.

I know it can be done but im worried its out of my skill zone....the website is php/mysql based.

Plaese can you tell me what options are available and how much work would be involved in setting this up.

Thanks

You need a "Crontab"
