php判断2个时间戳是否属于同一天

int time_zone = 8, daily_reset_time = 5;
time_t BetweenDays(time_t time1, time_t time2)
{
return (time1 + time_zone *3600)/3600/24 - (time2 + time_zone *3600)/3600/24;
}
/*
 * last_reset_time 为上次执行的每日重置时间
 * cur_time 为当前时间
 */
bool IsTimeToReset(time_t last_reset_time, time_t cur_time)
{
return BetweenDays(cur_time - 3600 * daily_reset_time, last_reset_time - 3600 * daily_reset_time) > 0;
}
