Die Roller problems

[krappleby025]

HI guys,

im having a bit of a problem with a function to roll a die..

here is the code i have created

********************

function Roll_Dice($die)
{
$die_roll = rand(1,$die);
return $die_roll;
}


#### testing function

$num_rolls = "0";
$die_rolls = "0";

while ($num_rolls <> "6")
{
while ($die_rolls <> "3")
{
Roll_Dice("6");
$roll . $die_rolls = $die_roll;
$die_rolls = $die_rolls + 1;
}
$num_rolls = $num_rolls + 1;
echo "Roll " . $num_rolls . " = " . $roll1 . " + " . $roll2 . " + " . $roll3 . " = " . $roll1+$roll2+$roll3 . "<br>";
}
*************

if any of you know about RPG you will understand what i am trying to do.. Create 6 rolls containing 3 dice each..

however. for some reason the function is not returning a valid number.. when running the script.. all i get is

exceeded 30 seconds..

if i remove most of the info to just leave the main programming i get a 0 only..

appreciate your help

Your problem with invalid numbers likely stems from the fact that your Roll_Dice() function returns a value, but you don't do anything with it.

I also do not know what this line:

$roll . $die_rolls = $die_roll;

is supposed to do, but I would be suprised if PHP will not give you a parse error on the line. If you're going to store multiple values, I recommend the use of an array.

Try:

<?php
function roll_dice ($die_size = 6)
{
	return rand(1,$die_size);
}

$number_of_rolls = 3;
$die_size = 6;
$rolls = array();

for ($counter = 0; $counter < $number_of_rolls; $counter++)
{
	$rolls[] = roll_dice($die_size);
}

print $number_of_rolls . 'd'. $die_size . ":";

foreach ($rolls as $roll)
	print ' ' .$roll;
	
print ' = ' . array_sum($rolls) . '<br>';
?>

  Roll_Dice("6");
        $roll . $die_rolls = $die_roll;

Now as as Sleipnir said, $roll . $die_rolls=$die_roll who knows what this is doing,
However, assigning the value of a variable that comes from a function outside of the function is not possible. because your variable $die_roll only exists inside yor function. you'd have to assign it like this:

$rolling=Roll_Dice(6);

So you get the value that the function returns.

Try that and see waht it does.
