yii 框架实现按天，月，年，自定义时间段统计数

$rangeTime = range(0, 23);

// $days = cal_days_in_month(CAL_GREGORIAN, $month, $year);
$days = date("t",strtotime($year . '-' . $month));
// 生成1-days的天
$rangeTime = range(1, $days);

$rangeTime = range(1, 12);

$stimestamp = strtotime($time);
$etimestamp = strtotime($time2);
// 计算日期段内有多少天
$days = ($etimestamp - $stimestamp) / 86400 + 1;
// 保存每天日期
for($i = 0; $i < $days; $i++){
  $newTimeStamp = $stimestamp + (86400 * $i);
  $rangeTime[] = date('Y-m-d', $newTimeStamp);
  $labels[] = date('d', $newTimeStamp) . Yii::t('backend', 'day');
}
