Sorry for the crappy explanation.

I need to create a unique ID when someone loads a page. I'm doing this via the function I posted above.

The page will have two adverts on it, one in (for example) header.php and one in a footer.php. I need to be able to use the same unique ID for both adverts.

How I was hoping it could be done was that header.php has the function in it to create the ID and then I can just use $OurID in the footer and it's the same value as it was in the header. The next time the page is loaded the value is changed to a new random ID.
