php取得系统启动时间长短实例代码

  1. //系统启动时间计算.
  2. $UPTIME = 32936982.68;
  3. $DAY = floor(($UPTIME / 86400)*1.0) ;
  4. $cal_day = $DAY * 86400 ;
  5. $cal_hour = $UPTIME - $cal_day ;
  6. $hour = floor(($cal_hour / 3600)*1.0) ;
  7. if ($hour
  8. $hour = "0".$hour ;
  9. }
  10. $cal_tmp = $hour * 3600 ;
  11. $cal_min = $cal_hour - $cal_tmp ;
  12. $min = floor(($cal_min / 60)*1.0) ;
  13. if ($min
  14. $min = "0".$min ;
  15. }
  16. $cal_sec = $min * 60 ;
  17. $sec = floor(($cal_min - $cal_sec)*1.0) ;
  18. if ($min
  19. $sec = "0".$sec ;
  20. }
  21. $ServerUptime = $DAY." 天, ".$hour.":".$min.":".$sec ;
  22. echo 结果输出: . $ServerUptime ;
  23. ?>

结果输出: 381 天, 05:09:042
