[Making Bineary Code]

Well Guys... I better hope ya good at PHP otherwise I registrated here for nothing lol :D

Well now ontopic again...

[b]Example:[/b]
I have the number 7 (or 10 or 12 or 123 etc etc)
$number = 7;

Now I want that the 7 will get splitted in 3 other numbers and on bineary way...
So that would be
2^0 = 1
2^1 = 2
2^2 = 4

1+2+4 = 7

So the output should be 1, 2, 4

Now I got this script:
[code]<?php
$decimaal = 7;

$binair = decbin($decimaal);
$stukjes = str_split($binair);

// str_split split vanaf links, maar we rekenen vanaf rechts
array_reverse($stukjes);

$delen = array();
foreach ($stukjes as $key => $stukje) {
    if ($stukje == 1) {
        $delen[] = pow(2, $key);
    }
}

print_r($delen);
/** OUTPUT:
*  Array
*  (
*     [0] => 1
*     [1] => 2
*     [2] => 4
*  )
**/
?>[/code]

What is the problem with this:
Well for example I do
$decimaal = 10;

The output will be not:
[code]Array
(
  [1] => 2
  [3] => 8
)[/code]

but is
[code]Array
(
  [0] => 1
  [1] => 4
)[/code]

other arrays must be equal to 0 then becaus the binary code would be for 10 in this example 0101

Now how should I do this :)

PS: if ya got a other code or something that likes on this sh1t i mean then also feel free to post
