统一编码
1.目前处理的文件类型有两种 txt html
2.文件的编码未知 要读取文件内容 内容编码最后统一转换成utf-8 最终入库
目前想用mb_convert_encoding($file_content,'utf-8',"auto"); 好像不行 求大神赐教!帮忙分析下(txt的复杂点)
回复讨论(解决方案)
用 mb_convert_encoding 大多不能得到正确的判断
所以 mb_string 扩展有了一个新成员 mb_check_encoding
这个函数可以准确的判定来源是否为指定的字符集
只不过你需要写代码来枚举可能的字符集:
if(mb_check_encoding($s, 'utf-8')) ....
elseif(mb_check_encoding($s, 'gbk')) ....
elseif(mb_check_encoding($s, 'big5')) ....
else ....

if(mb_convert_encoding($file_content,'ASCII')){ mb_convert_encoding($file_content,'UTF-8',"ASCII"); }elseif(mb_convert_encoding($file_content,'GB2312')){ mb_convert_encoding($file_content,'UTF-8',"GB2312"); }elseif(mb_convert_encoding($file_content,'GBK')){ mb_convert_encoding($file_content,'UTF-8',"GBK"); }elseif(mb_convert_encoding($file_content,'BIG5')){ mb_convert_encoding($file_content,'UTF-8',"BIG5"); }else{ mb_convert_encoding($file_content,'UTF-8',"auto"); }
还有有乱码

不明白你给出的连接反映的是什么
既然你已经发现 mb_convert_encoding 不准确了,那么你为什么还在用呢?
$file_content = '待转码的内容';$charset = '';if(mb_check_encoding($file_content, 'utf-8')) $charset = ''; //已是 utf-8 了无需转码elseif(mb_check_encoding($file_content, 'big5')) $charset = 'big5'; //big5 的码值范围小于 gbk,应先判断elseif(mb_check_encoding($file_content, 'gbk')) $charset = 'gbk'; //gb2312 是 gbk 的子集,只判 gbk 就可以了if($charset) $file_content = mb_convert_encoding($file_content, 'utf-8', $charset);

不好意思 刚才代码写错了
链接是测试结果 编码问题会影响解析的结果(以前只分析linux下生成的文件所以一直没发现这个问题) 谢谢 问题已经解决啦

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 enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

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.
