Convert associative array to indexed array

Don't think you have to, you can just access it by index as well.

I quickly put together this recursion function.

function assoc2indexedMulti($arr) {

    // initialize destination indexed array
    $indArr = array();

    // loop through source
    foreach($arr as $val) {

        // if the element is array call the recursion
        if(is_array($val)) {

            $indArr[] = assoc2indexedMulti($val);

        // else add the value to destination array
        } else {

            $indArr[] = $val;
        }
    }

    return $indArr;
}

Tested it on a small array, I hope it works OK on your array. If the array is large it might be an issue since it doubles the memory requirement.

Thanks, that worked! :)
