现在需要搜索一个字段中包含:猪,狗,牛三个词的数据,
请问,怎么才能让结果按照指定关键词排序,比如让结果数据按照其中包含了猪的排在前面,包含了狗的排在第二,牛的排在第三。
例如:
猪啊
牛啊
狗啊
狗啊
猪啊
牛啊
要让结果排序变成
猪啊
猪啊
狗啊
狗啊
牛啊
牛啊

加上order by 字段1,字段2,字段3
{
select * from 表名 order by 猪,狗,牛;
}应该就可以了
猪,狗,牛是在同一字段中的,楼上的不行。
可以这样写,例如字段名叫shengxiao
$sqlstr = "select *,IF(shengxiao='猪啊',1, IF(shengxiao='狗啊',2,3)) as s from table order by s";
加上order by 字段1,字段2,字段3
{
select * from 表名 order by 猪,狗,牛;
}应该就可以了
这样不行,猪,狗,牛不是字段,猪狗牛是数据
查询是这样的
$str="select id from biaoqian where (biaoti like '%猪%' or b.biaoti like '%狗%' or b.biaoti like '%牛%' or b.biaoti like '%猪狗牛%' ) order by id desc limit 10";
现在的搜索结果排序方式是按id的倒序排列,我想按照搜索结果包含的数据排列,
包含 “猪狗牛”的排在第一,然后包含猪的排在第二,包含狗的排在第三,最后是包含牛的
create temporary table T select '猪啊' as f union select '牛啊' union select '狗啊';select *, if(locate('猪', f), '猪',if(locate('牛',f),'牛', if(locate('狗',f),'狗',''))) as x from T order by find_in_set(x, '猪,狗,牛')
f x 猪啊 猪 狗啊 狗 牛啊 牛
order by xx like '%猪%', xx like '%狗%', xx like '%牛%' desc
搞定了,非常感谢

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.
