Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /data/multiserv/users/983917/projects/2245004/www/view.php on line 42
本地服务器调试没有出现这个警告,上传到远程服务器就出现了...而且我没有权限修改远程服务器的配置..只能从代码这里来解决

本地调试的apache已经display_error=on 没有出现这个警告
42行是哪行?一般情况下加个or die 会有提示.
mysql_query($comment,$mylink) or die(mysql_error());
$result5=mysql_fetch_array($levelquery);
$result4=mysql_fetch_array($commentquery,$mylink);
$result3=mysql_fetch_array($result2);
有mysql_fetch_array的都报错了

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,

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.
