回复讨论(解决方案)
你的问题呢??
if(!$numRows=mysql_num_rows($link,$result))//获取记录条数
int mysql_num_rows ( resource $result )
这个方法只有一个参数,你传两个当然有警告了。
if(!$numRows=mysql_num_rows($link,$result))//获取记录条数
int mysql_num_rows ( resource $result )
这个方法只有一个参数,你传两个当然有警告了。
那我要怎么修改呢
1、你只贴出了代码,并没有说明你遇到了什么问题
难道是在出 灯谜?
2、php_mysql 和 php_mysqli 是两个不同的扩展。你同时使用他们,就不怕会绕昏?
3、showpagelink 函数中使用了 php_mysql 扩展的函数,而在调用该函数前使用的是 php_mysqli 扩展的查询( $result=mysqli_query($link,$query);)
你把问题藏代码里面了吗,谁知道你要问什么啊

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,

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.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
