所以我回来了，我将在这里添加一个更好的注释代码：无法编辑旧答案，因为我删除了我的帐户并忘记取消：|
无论如何，您问的是如何操作数据。这是一个简单的数组，所有内部数组都是从一周开始到结束的总和。现在，你可以用不同的键来存储它们，为了简单起见，我只使用了默认分配。
$results=array(

编辑：
添加了一个新的 while 循环来解决空周的问题。
注意 d/m/Y 不是 strtotime 可识别的格式，它将被读取为 m/d/Y。转换it refer to this question.
编辑-2：
回答您的评论。好的，所以关于跨度的事情是我制作了它们，以便如果跨度从 2020-01-01 到 2020-01-08 并且第二个从 2020-01-08 到 2020-01-15 应该在哪里工作2020-01-08 的时间转到第 1 周还是第 2 周？
当您将 $entry_time
如果您希望容器跨越 2020-01-01 和 2020-01-08 和 2020-01-09 和 2020-01-16 之间，并且两端都为包括的。现在，我不打算写这部分，因为它真的取决于你想要如何定义你的结局。
您的问题是您是否可以将时间更改为当前时间以外的其他时间？当然，只需更改此行。
$time=strtotime(date('Y-m-d'));
//to
$time=__TIME__YOU_WANT_IN_SECONDS__;
//or
$time = strtotime(__THE_DATE_YOU_WANT__); // eg. 01/01/2020
// now this is the time to compare all other dates to
