Random Numbers

[Ricardo]

Does anyone know how to make $rand(0,3) very common, $rand(4,6) rare, and
$rand(7,9) extremely rare and link it to echo one number?

eg:

blah 3-3 blah would be very common or 2-2 or 2-1 etc.

Also, if it helps, the 0-3 has a 75% "success rate", 4-6 has 40, and 7-9 has
10.

Thanks alot everyone

Re: Random Numbers

$tmp=rand(0,100 )
if($tmp<=75)
{
echo rand(0,3);
}
elseif($tmp<=95 )
{
echo rand(4,6);
}
else
{
echo rand(7,9);
}

is that what you want?

How does that happen? that's 125%!

Anyway, assuming that the 75 above was a 50, do this:

Create an array. The first 50 elements between 0 - 3. The next 40 is 4 -
6, and the last 10 are 7 - 9. Then pick a random number between 0 and
99. Statistically, your percentages should work out.
