获取指定日期为星期几
之前在项目开发过程当中,需要写一个月历和一个周历,由于当时项目经验太少,保存时间的时候将格式化后的时间保存到数据库,并且还要判断当前一个月内所有天数里发生的事件,还用到了给出指定的日期判断是星期几的功能。所以,对后期时间处理造成了不必要的麻烦。
后来从网上查了一些相关资料,结合自己学习的知识,编写了一个简单的function,现将代码贴出,仅供大家参考,有不足之处,忘多多批评。

12. $year = $datearr[0]; //获取年份
13. $month = sprintf('%02d', $datearr[1]); //获取月份
14. $day = sprintf('%02d', $datearr[2]); //获取日期
15. $hour = $minute = $second = 0; //默认时分秒均为0
16. $dayofweek = mktime($hour, $minute, $second, $month, $day, $year); //将时间转换成时间戳
17. return date("w", $dayofweek); //获取星期值

Fermat's last theorem, about to be conquered by AI? And the most meaningful part of the whole thing is that Fermat’s Last Theorem, which AI is about to solve, is precisely to prove that AI is useless. Once upon a time, mathematics belonged to the realm of pure human intelligence; now, this territory is being deciphered and trampled by advanced algorithms. Image Fermat's Last Theorem is a "notorious" puzzle that has puzzled mathematicians for centuries. It was proven in 1993, and now mathematicians have a big plan: to recreate the proof using computers. They hope that any logical errors in this version of the proof can be checked by a computer.

PyCharm is a powerful Python integrated development environment that provides a wealth of development tools and environment configurations, allowing developers to write and debug code more efficiently. In the process of using PyCharm for Python project development, sometimes we need to package the project into an executable EXE file to run on a computer that does not have a Python environment installed. This article will introduce how to use PyCharm to convert a project into an executable EXE file, and give specific code examples. head

1. Let me first talk about the method I used at the beginning, maybe everyone is using it too. First, open [View]——]Remarks Template[. 2. A place where you can actually see the date after opening it. 3. Select it first and delete it. 4. After deleting, click [Close Master View]. 5. Open the print preview again and find that the date is still there. 6. In fact, this date was not deleted here. It should be in the [Handout Master]. Look at the picture below. 7. Delete the date after you find it. 8. Now when you open the preview and take a look, the date is no longer there. Note: In fact, this method is also very easy to remember, because the printed handouts are handouts, so you should look for the [Handout Master].

Excel software has very powerful data processing functions. We often use excel software to process various data. Sometimes when we enter a date in an excel cell, the date in excel changes to a pound sign. How can we display the data normally? Let’s take a look at the solution below. 1. First, we put the mouse on the column width line between columns AB, double-click and adjust the column width, as shown in the figure below. 2. After the column is widened, we find that numbers are displayed in the cells instead of dates. This is definitely incorrect. Then we should check the format of the cells, as shown in the figure below. 3. Click the "Number" option in the "Home" tab, and click "Other Number Format" in the drop-down menu, as shown in the figure below.

Question: How to determine whether the date is the previous day in Go language? In daily development, we often encounter situations where we need to determine whether the date is the previous day. In the Go language, we can implement this function through time calculation. The following will be combined with specific code examples to demonstrate how to determine whether the date is the previous day in Go language. First, we need to import the time package in the Go language. The code is as follows: import("time") Then, we define a function IsYest
