PHP用MYSQL做数据库时，内容字段到底有没必要分表呢？
比如有一个表里有个 id name content
那这个content我有没必要 经过一些处理
分散到10个表里去？
想知道如果分表 在多少量级别数量下 对比 才会有效率提升 或者根本没必要？
回复讨论(解决方案)
这个也不好说，以我个人的经验我会在其他10个表加这个表的id而不是content，一般情况id跟content相比占用的空间小些。
还有一点就是：id一般是唯一标示
主表 id name
分表有十个
id aid content 这里边的aid对应主表里的id 我是这种想法
没有必要！
即使是要分表，也不是你的这种分法
没必要把 如果要读取的话 还要到10个表里读取出来再拼?

不是 是固定的
文章表是 content : id cid title
栏目表是 channel: id cid name
然后不同栏目对应不同的 分表 比如 contet01 content02 content03 字段是 id aid content
比如 我要找文章ID为2 的 内容
那需要先找到，ID为2属于栏目几，比如ID为2的文章 属于栏目3
栏目3对应 的内容表是 content03
那程序就直接从 content03 中找 aid = 2 的 content字段值
那程序就直接从 content03 中找 aid = 2 的 content字段值 ？？？？
这可能吗？
那程序就直接从 content03 中找 aid = 2 的 content字段值 ？？？？
这可能吗？
不是 程序如果要找aid=2的 内容，首先在 aid=2的 文章表中 找到 对应的栏目ID 比如是栏目3
然后 栏目3中，有设定，所有归于栏目3的内容 都在 content03表里
然后，程序就去03表里找aid=2的 content值 并输出啦
中间是由栏目表做指定中转的
不是自找麻烦吗？

以前我在用ASP的一款CMS时 它是这样设计的 用的是access数据库 分表 以让数据多时 可以效率高一些
但我不知道mysql里这样分的话 到底有没意义了 所以这里问下大家啊
分表也不是你说的那种分法，如果有1千个栏目，岂不是要加1千个表？
完全没有必要把文章分表和栏目表弄在一起。
如果文章要分表，可以使用文章id来分表。
例如文章的id%10 会得到 0,1,2,3,4,5,6,7,8,9，这几个就是分表的表名。
可以根据id来判断内容在哪个分表。
例如要找id=2的文章内容。可以用$id%10 得出 2，然后直接在content02中读取内容。
没有必要！
即使是要分表，也不是你的这种分法
有必要这样做吗?
文章
id title 描述 (原谅我英语不好,想不起来了)
内容
id content
有必要分开吗? char int 等一些是定长的字段 和 nvarchar text 等自动分表?

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
How do you handle exceptions effectively in PHP (try, catch, finally, throw)?
Apr 05, 2025 am 12:03 AM
In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.
Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error).
Apr 08, 2025 am 12:03 AM
There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.
What is the difference between include, require, include_once, require_once?
Apr 05, 2025 am 12:07 AM
In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.
