Array(

Not sure if this is exactly what your looking for.

function array_remove_null($array) {
    foreach ($array as $key => $value)
    {
        if(is_null($value))
            unset($array[$key]);
        if(is_array($value))
            $array[$key] = array_remove_null($value);
    }
    return $array;
}

Update (corrections):

function array_remove_null($array) {
    foreach ($array as $key => $value)
    {
        if(is_null($value))
            unset($array[$key]);
        if(is_string($value) && empty($value))
            unset($array[$key]);
        if(is_array($value))
            $array[$key] = array_remove_null($value);
        if(isset($array[$key]) && count($array[$key])==0)
            unset($array[$key]);
    }
    return $array;
}

I'm sure better checking and making this more robust might help the solution.
