没看明白哪里有难点, 每天一次定时去数据库里分别取就是了 三天内的记录中筛选.
如果是时间问题,有很多种方案,比如你设定一个起始日期,拿现有的日期去和它对比就得到现有的日期在哪一个三天的周期内,然后between and 查询就是了
$s = strtotime('2013-06-15 00:00:00');
$e = time();
$arr = array(
'100,2113',//时装 3
'100,2114',//奢华、 6
'100,2115',//人物、9
'103,2124',//生活、 12
'102,2120',//街拍、15
'100,2122',//美容、 18
'100,2123',//明星 、
'104,2127',//测试、
'104,2128',//图库、
'104,2128,3770',//化妆品、
'104,2142',//试用、
'105,2130',//品牌、
'105,2137',//秀场、
'100,2112',//导购
); //42
$days = floor(($e-$s)/(24*60*60));//取得今天到我第一次程序执行时的天数
$key = floor($days/3);//当超过42天$key值就不对了
这个$key的获取要怎么写才好呢
$arr[$key] 这就是我当天要取得的分类
就是说你程序都已经OK了只是当超过42天就出问题了对吧?
那在你
$days = floor(($e-$s)/(24*60*60));//取得今天到我第一次程序执行时的天数
$key = floor($days/3);//当超过42天$key值就不对了
之间加一个
$days = fmod($days,count($arr)*3);
$days = floor(($e-$s)/(24*60*60));//取得今天到我第一次程序执行时的天数$days = fmod($days,count($arr)*3);//$days总是小于一轮循环的天数$key = floor($days/3);//当超过42天$key值就不对了

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.

To protect the application from session-related XSS attacks, the following measures are required: 1. Set the HttpOnly and Secure flags to protect the session cookies. 2. Export codes for all user inputs. 3. Implement content security policy (CSP) to limit script sources. Through these policies, session-related XSS attacks can be effectively protected and user data can be ensured.

Methods to optimize PHP session performance include: 1. Delay session start, 2. Use database to store sessions, 3. Compress session data, 4. Manage session life cycle, and 5. Implement session sharing. These strategies can significantly improve the efficiency of applications in high concurrency environments.

In PHP, you can use the session_name() function to configure the session name. The specific steps are as follows: 1. Use the session_name() function to set the session name, such as session_name("my_session"). 2. After setting the session name, call session_start() to start the session. Configuring session names can avoid session data conflicts between multiple applications and enhance security, but pay attention to the uniqueness, security, length and setting timing of session names.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
