while loop problem

[skoff]

Hi everyone! Here's my problem!
What i want to do is for each goal that is scored i want to generate a number of passes between 0 and 2. What i have right now is working i just dont know how to integrate the passes. I want the passes to appear right after the goal number just like this :

Goal #1 (passes #1, passes #2), Goal #2 (passes #1), Goal #3 etc..

and if passes = 0 i dont want to see the parentheses..

$i=1;
$goals=5;
$passes = rand(0, 2);

while ($i<=$goals) 
{
echo "Goal #" . $i . ",";
$i++;
}

Thanks to all of you i hope im clear :)

So, you want the following list (or something like it)?:

#1 (1),
#2 (2),
#3 (1),
#4 (2)

If so:

<?php

# Customization variables
$goals = 5;
$passes = range(0, 2);

//----

$max_pass = (count($passes) - 1);
if($max_pass >= 0) {
  for($i = 1; $i < $goals; $i++) {
   if($i > 0) {echo ",\n";}
   echo 'Goal #' . $i . ': ' . $passes[rand(0, $max_pass)];
  }
}

?>

I was going to post this earlier, but noticed that Readie had posted already, but anyway this is a bit different...

I would use for() loops, rather than while(), since you know the number of iterations before commencing the loop and is less prone to error. And I assume that $passes should be inside the goals loop and random for each goal?

$goals = 5; 
$maxPasses = 2; 
$strGoals = ''; 
for ($g=1; $g<=$goals; $g++) { 
  $passes = rand(0, $maxPasses); 
  $strGoals .= ', Goal #'.$g; 
  if ($passes > 0) { 
    $strPasses = ''; 
    for ($p=1; $p<=$passes; $p++) { 
      $strPasses .= ', passes #'.$p; 
    } 
    $strGoals .= ' ('.substr($strPasses,2).')'; 
  } 
} 
echo substr($strGoals,2);
