[SOLVED] Random Number Problem

[burnside]

Hey, I have a little bit of code :

 

 

 $num = rand(1,10); 

echo $num;
echo $num;
echo $num;

 

And it gived me the same number for all 3 echo's witch is what is expected but rather then having three $numa $numb etc ... is it possible to have $num not display the same number twice?

 

if that makes sence?

You don't actually change $num in between the echo calls, why in the world would you think it would be different? =/

 

How about:

<?php
for ($i=0;$i<3;$i++) {
    $num[] = rand(1,10);
}
echo $num[0];
echo $num[1];
echo $num[2];

Did you read your code after your wrote it? You only call the rand() function one time and then echo that number three times. How would it possibly produce more than one random number?

Exactly. =P

Additionally you could throw it into a function.

 

<?php
function newNum() {
     $num = rand(1,10);
     return $num;
}

echo newNum();
echo newNum();
echo newNum();
?>

 

And as the others have said. If you only randomize once, you only get one random number. If you roll a dice and get a 6, if you look at it two more times without rolling it, it's still a 6   I hope lol.
