如何返回过去的年数？

我和我的朋友正在为 IRC 机器人编写一个相当基本的正常运行时间脚本。

这是我们的代码：

function Uptime()
{
    global $uptimeStart;
    $currentTime = time();
    $uptime = $currentTime - $uptimeStart;
    $this->sendIRC("PRIVMSG {$this->ircChannel} :Uptime: ".date("z",$uptime)." Day(s) - ".date("H:i:s",$uptime));
}

$uptimeStart 在脚本运行时立即设置，如 time();

由于某种原因，当我执行此函数时，它从 364 天零 19 小时开始。我不明白为什么。

My friend and I are working on a fairly basic uptime script for an IRC Bot.

Here's our code:

function Uptime()
{
    global $uptimeStart;
    $currentTime = time();
    $uptime = $currentTime - $uptimeStart;
    $this->sendIRC("PRIVMSG {$this->ircChannel} :Uptime: ".date("z",$uptime)." Day(s) - ".date("H:i:s",$uptime));
}

$uptimeStart is set immediately when the script runs, as time();

for some reason when I execute this function, it starts at 364 days and 19 hours. I can't figure out why.

您的 $uptime 不是应在 date() 中使用的时间戳，而是时间差。你有一定的秒数，而不是时间戳（与实际日期相对应。

只需使用类似这样的东西来计算（快速计算，为 1 天、2 小时等添加一些额外的大脑）；）

 $minutes = $uptime / 60;
 $hours   = $minuts/60 ;
 $days    = $hours / 24

等等

Your $uptime is not a timestamp as should be used in date(), but a difference in time. You have an amount of seconds there, not a timestamp (that corresponds with an actual date.

just use something like this to cacluate (quick one, put some extra brain in for things like 1 day, 2 hours etc) ;)

 $minutes = $uptime / 60;
 $hours   = $minuts/60 ;
 $days    = $hours / 24

etc

如果您有 5.3 或更高版本，请使用 DateTime 和 DateInterval 类：

$uptimeStart = new DateTime(); //at the beginning of your script

function Uptime() {
  global $uptimeStart;
  $end = new DateTime();

  $diff = $uptimeStart->diff($end);

  return $diff->format("%a days %H:%i:%s");
}

If you have 5.3 or above, use the DateTime and DateInterval classes:

$uptimeStart = new DateTime(); //at the beginning of your script

function Uptime() {
  global $uptimeStart;
  $end = new DateTime();

  $diff = $uptimeStart->diff($end);

  return $diff->format("%a days %H:%i:%s");
}

通过在该时差上调用 date() 不会得到任何有意义的信息。您应该将这个时间差逐渐除以年、月、日、小时，所有这些都以秒为单位。这样您就可以得到这些条件下的时差。

$daySeconds = 86400 ;
$monthSeconds = 86400 * 30 ;
$yearSeconds = 86400 * 365 ;

$years = $uptime / $yearSeconds ;
$yearsRemaining = $uptime % $yearSeconds ;

$months = $yearsRemaining / $monthSeconds ;
$monthsRemaining = $yearsRemaining % $monthSeconds ;

$days = $monthsRemaining / $daySeconds ;

..等等以获得小时和分钟。

You won't get anything meaninful by calling date() on that time difference. You should take that time difference and progressively divide with years, months, days, hours, all measured in seconds. That way you'll get what the time difference in those terms.

$daySeconds = 86400 ;
$monthSeconds = 86400 * 30 ;
$yearSeconds = 86400 * 365 ;

$years = $uptime / $yearSeconds ;
$yearsRemaining = $uptime % $yearSeconds ;

$months = $yearsRemaining / $monthSeconds ;
$monthsRemaining = $yearsRemaining % $monthSeconds ;

$days = $monthsRemaining / $daySeconds ;

.. etc to get hours and minutes.
