$file = ROOT_PATH . '/stat/' . $host . '/stat.log';
$str = @file_get_contents($file);
$arr = [];
if (empty($str))
{
    mkdir(ROOT_PATH . '/stat/' . $host);
    $arr = [0,0,$now];
}
else
{
    $arr = explode(',', $str);
}

$arr[0]++;
$arr[1] = substr($arr[2], 0, 10) < date('Y-m-d') ? 0 : ($arr[1] + 1);
$arr[2] = $now;

@file_put_contents($file, implode(',', $arr));

$data = [
