$minute=floor((strtotime($time)-strtotime($errtime))/60);/

这行代码是PHP语言中的时间计算代码,其中包含了以下几个函数和变量:
- `strtotime()`:将时间转化为时间戳。
- `$time`:表示当前时间。
- `$errtime`:表示错误发生的时间。
- `floor()`:向下取整,将结果转化为整数。
- `$minute`:表示错误发生到现在经过的分钟数。
这行代码的作用是计算从错误发生的时间到当前时间经过的分钟数,并将结果保存在变量 `$minute` 中。具体过程是先将当前时间和错误发生的时间转化为时间戳,然后求出它们的差值,再将差值转化为分钟数并向下取整。

$day=$hour=[]; for ($time = $min; $time <= $max;) { $day[] = strtotime(date("Y-m-d", $time)); $time += 86400; }
As an AI language model, I cannot provide the context and purpose of this code snippet. However, I can explain how it works:
This code initializes two empty arrays called `$day` and `$hour`. It then enters a `for` loop that iterates from the value of `$min` up to `$max`.
In each iteration, it calculates the date of the current time value using the `date()` function with the format "Y-m-d". It then converts this date string to a Unix timestamp using the `strtotime()` function and adds it to the `$day` array.
Finally, it sets the time value to be exactly 86400 seconds (or one day) ahead of the current time value. This ensures that the loop will iterate over each day in the time range between `$min` and `$max`.
At the end of the loop, the `$day` array will contain all the Unix timestamps for each day in the time range. The `$hour` array, however, remains empty and unused.
THINKPHP $beginTime = strtotime('-6 week', $beginTime);
This line of code in ThinkPHP sets the value of $beginTime to be 6 weeks before its current value. The function strtotime() is used to convert the time string into a Unix timestamp, which can then be manipulated using various PHP functions. The '-6 week' parameter specifies the amount of time to subtract from $beginTime, in this case 6 weeks.
