hi i want to exclude sat and sun from this function.currently this is calculating all days
function human_timing_mins_hrs_days_only($time)
{
    $time = time() - $time; // to get the time since that moment
    $tokens = array (
        86400 => 'day',
        3600 => 'hour',
        60 => 'min',
        0 => 'min'
    );
    foreach ($tokens as $unit => $text) {
        if ($time < $unit) continue;
        $numberOfUnits = floor($time / $unit);
        return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
    }
}
