$rank = rand(4, 10);

Hi Glacai...
thanks for your reply and wecome to WebmastersWorld im new to srank in fact whole cgi scripting ect
learning sinse few months now ... so i just include this ;
$rank = rand(4, 10); or do i need to include a extra line as well to start the random tool? like: srand; my book says you may only include once ... so i add to top of script this?corect me if i am wrong; srand; then
$rank = rand(4, 10); thats all right? thx

Hi StopSpam, thanks for the welcome but I been around coming up to a year! but all the help I can give is usually already answered. Anyway I don't think you need to use srand in the latest php but if you do yes, you should only seed it once each execution. Sorry forgot, you need to seed with a number, usually something made from the date.

Sorry, yeah its nearly the same except it only takes max number, you don't need to call srand but I would look it up to find the best way to seed it. $rank = rand(7) + 4;
