RE: [PHP] rand(), mt_rand(), and my inability to make either of them random.

2001-01-26 Thread Robert Collins 

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);

}
?

I have this scriptlet:

$items = 6;
$randnum = rand(1,$items);
echo $randnum . "brbr";

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 . "brbr";

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?

Thanks.  It doesn't need to be completely random, just, more random than
"1".  The occasional 3 would be enough for me.

And,t hank you very very much.  You forgot the quotes around the U, btw.

2001-01-26 Thread April 

lol, nm, you weren't.  Why does it return Warning: Use of undefined constant
U - assumed 'U' in c:\apache\htdocs\temp\random.php on line 4 if I don't use
quotes, though?

ayway, I'm going to give up on this.  Thanks, though.
