一个关于时间问题
当前的日期通过控件获得：
- PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$thisday = $_GET['calendar'];
现在我想求这个日期的前一天（查询日历日期的前一天），怎么求？
注：日历的字符串形式 Y-m-d
------解决方案--------------------
-1day
------解决方案--------------------
echo date('Y-m-d', strtotime("-1 day $thisday"));
------解决方案--------------------
如果$_GET['calendar']的时间格式类似“2012-02-14 11:56:30”，则先转换为time格式：strtotime($_GET['calendar'])
然后减去一天的秒数就可以啦：strtotime($_GET['calendar'])-60*60*24

How to change Ubuntu's apt-get update source?
Jan 05, 2024 pm 03:40 PM
Manually modify Ubuntu's apt-get source 1. Use the ssh tool to connect to Ubuntu (I use xshell) 2. Type cd/etc/apt/3 on the command line and back up the source.list file in this directory (you must have sudo permissions) ), then there is a source.list.bak file. 4. Clear the source.list file content (note: it cannot be restored after clearing, so you need to perform the previous step to back up the file in advance). At this time, use sudo to prompt that the permissions are insufficient. Switch directly to the root user and execute this command. 5. Use vim to open source.list, press the i key to enter the editing mode, paste the source address to be modified, and then press

How does SpringBoot use entities to receive multiple parameters passed by the Get request?
May 19, 2023 pm 06:01 PM
1. The first method of the Controller layer receiving parameters without any annotations is the simplest. I seriously doubt why it was not used before. Who knows. . But this time it really worked. The simplest way is to add the Controller interface without adding any annotations! ! ! SpringBoot handles this automatically. The code is as follows: /***@authorzhangzhixiang*@sincev1.0.0*/@RestController@RequestMapping(path="/ui/institution")publicclassInstitutionManagemen
