Role a 6 to win! PHP Code - php

Question

I'm currently learning how to use do/while loops in PHP through codeacademy. I'm working on a challenge where you create a six-sided die and continue rolling until you get a six. Here's what I've come up with so far:
<?php
$roll = 1;
do {
echo “Roll Number " . $roll . ". Begin rolling for a 6.";
} while ($roll != 6); {
for ($rollNumber = 1; $roll != 6; $roll ++) {
$roll = rand(1, 6);
echo "On roll number " . $rollNumber . "You got a " $roll ".\n";
};}
?>
I though the best way to get started is by creating a roll variable that we can use once for the do loop to check if it's working:
$roll = 1;
I set the value to one instead of zero, because there's no zero number on a die, and we'll assume the player first rolls a one. Next I want to check if the do loop is working so I echo the following:
do {
echo “Roll Number " . $roll . ". Begin rolling for a 6.";
}
After making sure the do loop worked, I create the while condition:
while ($roll != 6) {
Then I want to create a rollNumber variable to keep track of what roll I'm on and increment it:
for ($rollNumber = 1; $roll != 6; $roll ++) {
next I set the value of the roll variable so that it generates a random number between 1 and 6:
$roll = rand(1,6);
Finally I want to echo the message "On roll number you got a ." :
echo “On roll number “ . $rollNumber . "You got a " $roll “.\n";}
For some reason the code's not working. Any suggestions or help would be much appreciated! Thanks.

Answer 1

You were on the right track with a while loop and rand(). The only other thing you needed was to set a count variable to display the roll number (you can just increment this variable on every "roll").
Your code could be simplified to this:
$c = $n = 1;
while ($n != 6) {
echo 'on roll number ' . $c++ . ' you rolled a ' . $n = rand(1, 6) . "\n";
}
Here's an example

Answer 2

You've made this way too complicated. There's no need for two loops.
$rolled = 0;
$numbers = range(1, 6); //generate array with 1-6
$counter = 0;
while($rolled!=6)
{
$counter++;
shuffle($numbers); //shuffle array
$rolled = $numbers[0]; //grab first item
echo '<br/>(Roll ' . $counter . ') ' . $rolled;
}

Answer 3

Why not have a function that returns the result of a roll, and then a loop that calls this function until it returns a 6?
<?php
function roll() {
return mt_rand(1, 6);
}
$roll = 1;
do {
if (roll() == 6) {
printf('You rolled a 6 on roll %d.', $roll);
break;
}
$roll++;
} while (0);
This do/while loop continues until the roll() function returns a 6.
