数据库中不乱码?你用什么工具查看的
用Mysql Front
乱码字段的类型是longblob的
查询之后显示
[1] => array(7) {
["question_index"] => string(1) "2"
["question_content_text"] => string(21) "小鸟会不会飞?"
["question_type"] => string(9) "问答题"
["answer"] => string(16) "????????????"
["user_answer"] => string(1) "2"
["question_score"] => string(2) "10"
["user_score"] => string(1) "0"
}
从长度 16 上看,你的 answer 字段不是 utf-8 编码的吧?
echo base64_encode($ar[1]['answer']); 贴出结果

echo base64_encode($ar[1]['answer']);之后出现:
v8nE3Lvho6y/ycTcsru74Q==
$s = base64_decode('v8nE3Lvho6y/ycTcsru74Q==');var_dump($s);
是 gbk 编码的
你需要在查询前执行 set names utf8 指令
或在输出前转码

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.
