help with random

Frihost Forum Index -> Scripting -> Php and MySQL

I have a little script that puts a random number between 0 and 25

Code:

<?
srand(time());
$random = (rand()%26);
?>

Is this a good script to get a random number or not?

no I'm will to put in the page title and somewhere on the page a random username random link and a random message (all with the same number)
I was thinking for the title:

Code:

<title>Join <?php echo "$" . "us" . $random ?></title>

That could become $us0 wich will result in golles, but it doesn't the page title would be "Join $us1"

So can someone tell me what I'm doing wrong?
and if the random code is good?
thanks in advance!

//golles

Don't really understand what you mean, but instead of

Code:

$random = (rand()%26);

You could also do:

Code:

$random = rand(0, 25);

Seems easier to me...

well the most elegant way of solving this would be a array for $us

Code:

$us = array(...,..,..);
echo "<title>Join ". $us[$random]."</title>

another way would be

Code:

$username = "us" . $random;
echo "<title>Join ". $$username."</title>

thanks. a mate made a script for me and is now explain the array thing to me.
thanks anyway!

Might want to use microtime()-(time()*1000) instead of time().

That's usefull if it has to be completely random, but in this case it seems to me like that's not really important.
