hi all
i am trying to create a function that finds all the combinations of a given array and to store each combinatin in to a new array ie

array(1,2,3) would create seven new arrays (1),(2),(3),(1,2),(1,3),(2,3),(1,2,3),

my first function calculateNumberOfCombinations() works fine as this is the result when i use print_r() i get this;
Array ( [0] => Array ( [0] => 1 ) [1] => Array ( [0] => 2 ) [2] => Array ( [0] => 3 ) ) Array ( [0] => Array ( [0] => 1 [1] => 2 ) [1] => Array ( [0] => 1 [1] => 3 ) [2] => Array ( [0] => 2 [1] => 3 ) ) Array ( [0] => Array ( [0] => 1 [1] => 2 [2] => 3 ) ) which is an array of all my arrays as described above.
question is how do i separate each array from the large array.

the code contains a recursive function that i was toying with but no joy.

Very grateful for any help,advise or even counselling (im cracking up) .would be very much indebted to solver.
PHP Code:
<?php
function calculateNumberOfCombinations($newArray,$len)
{
    if (
$len count($newArray))
        return 
'error';
    
$out = array();
    if (
$len == 1) {
        foreach (
$newArray as $v)
            
$out[] = array($v);
        return 
$out;
    }
    
$len--;
    while (
count($newArray) > $len) {
        
$b array_shift($newArray);
        
$c calculateNumberOfCombinations($newArray$len);
        foreach (
$c as $v) {
            
array_unshift($v$b);
            
$out[] = $v;
        }
    }
    return 
$out;
}
$numberOfCombos = array(1,2,3);
$allArrays = array();
$newArray=array();

for(
$count=2;$count<=count($numberOfCombos); $count++)
{
    
//counted at 2 as i dont have to worry about singles
    
$newArray calculateNumberOfCombinations($numberOfCombos$count);   
    
//findArray($newArray);
    
    // for testing purposes
     
print_r($newArray);
}

/*function findArray($newArray)
{
   
    if (!is_array($newArray))
        die('not array');
    foreach ($newArray as $value) {
        if (is_array($value)) {
            findArray($value);
            
        } else {
            return($value);
            //echo $value.'';
           //would need to create a new array with result from foreach loop how? 
        }

        echo '<br />';
    }
}
