Changing Array Key Values

Well here we go again. :-P Obviously.

At the moment, I've got an array with the values 8, 4 and 2. Of course, accompanied by the keys 0, 1 and 2.
Now, since those keys can also address the roundtype, I can enter it as 1, 2 and 3. Which would be far more convenient than sending 1::8, 2::4, 3::2 and exploding it as I go.

So, how do I shift somewhat these keys?

I wouldn't use the index as a value in the equation, purely because indexes must be unique and so when you want the same round value, you'll have to refactor your code. How about something like a multidimensional array? Such as the following...

php Code:

$aValues = array
(
    array(1, 5.5555),
    array(3, 7.7777)
);

foreach ($aValues as $aValue)
{
    echo 'Result = ' . round($aValue[1], $aValue[0]) . '<br />';
}

Well, sort of helped I guess.

I can't figure out how to display the brackets though.

Currently I've got:

PHP Code:


		
			
    foreach (countBrackets($totalPlayers) as $key => $value) {
        $key++;
        $keys = $key.'::'.$value[1];
        array_push($bracketArray, $keys);
    }
    
    
    print_r($bracketArray);

Now, this displays Array ( [0] => 1::16 [1] => 2::8 [2] => 3::4 [3] => 4::2 ) but now how I want it to.

How do I now, print out the 4 rounds, which each corresponding number of brackets in that round.
It should be displayed somewhat like this:

Code:

Round 1     Round 2     Round 3     Round 4

1           1           3           8

2                                   

3           3           

4

5           6           8

6

7

8           8

Of course, each value from 1 to 8 in the first round will be printed vertically with each an unique top: Xpx; value. Same goes for round two, but then automaticly with a new left: Xpx; and top: Xpx; value.

Well, it would be a HUGE help you you guys could help me out here.

Do you mean something like:

PHP Code:


		
			
$round = 2;

$data = Array(8, 2, 4);



echo(array_key_exists(--$round) ? $data[$round] : 'Invalid round');

Or something like that?

Like this?

PHP Code:


		
			
<?php
function bomb($array) { return explode('::', $array); }
$bracketArray = array ( 
            0 => '1::8',
            1 => '2::4',
            2 => '3::2',
            3 => '4::1'
            );        
$bracketArray = array_map('bomb', $bracketArray);
foreach($bracketArray as $bracket)
{
    
    echo'<div style="width:90px; float:left;">',
        '<strong>Round ', $bracket[0], '</strong><br />';
        
    for($i=0; $i < $bracket[1]; $i++)
    {
        echo '<span style="float:left;clear:both;">',$i + 1,'</span>';
    }
    echo'</div>';
}

hope i havent missed the mark

sketch, I think I love you. That's exacly what I meant! Filling in the values will be done dynamicly, so no problem there! Thanks a lot!

Kalle, thanks for the help as well, although it was not what I meant! Non the less. :-)
