this is a function that I wrote to solve this problem, but it is almost
impossible to get a truly random number you can get somthing pretty close by
seeding with somthing like the time function, using the seconds since epoch
and this should be hard to duplicate.
<?php
function random_number($config, $lownum, $highnum){
$time = date(U);
$seed = srand($time);
$rand = rand($lownum, $highnum);
echo "<FONT FACE=\"$fontstyle\" SIZE=\"$fontsize\"
COLOR=\"$fontcolor\">$rand</FONT>";
$lownum = "1";
$highnum = "100";
random_number("config.inc.php", $lownum, $highnum);
}
?>

Subject: [PHP] rand(), mt_rand(), and my inability to make either of
them random.
I have this scriptlet:
$items = 6;
$randnum = rand(1,$items);
echo $randnum . "<br><br>";
Always, no matter how many times I hit refresh, it'll always return the
lowest possible value, in this case 1. If I have rand(4,$items), it returns
four.
So I tried mt_rand(), with this:
$items = 6;
$randnum = mt_rand(1,$items);
echo $randnum . "<br><br>";
This always, without fail, returns the highest possible value. 6 in this
case.
I'm using Apache/4.0.3pl1 on Windows 2000, locally, just to develop. Could
this be a cache type problem? Could the gods be conspiring to drive me
steadily insane?
