Random page displayed by importance

[Haraldo]

I'd like to display a page chosen by random from several pages, but the pages need to be ranked with importance. E.g

Page1 = 50% Page2 = 30% Page3 = 20%

The percentages can change, what above shows is that Page1 is the most important and will show itself 50% of the time, Page2 30% of the time and Page3 will appear but just less frequently at 20% of the time.

Is there a function that can do this? Or will i need to create some logic.

Thanks for any support.

The simplest (and classic logic:
Get a (pseudo)random number in range 0..99 with rand(0,99).
if n < 50 - select 1st page
else if n < 80 - select 2nd page
else - select 3rd page.
Don't forget to seed the random number generator with srand (see PHP manual).
