zend guard对php代码加密 zend optimizer解析
今天搞了一天，对自己的一个小项目进行zend guard加密。完了之后装上zend optimizer解析器，可以访问路由的时候，一直报‘Incompatible file format: The encoded file has format major ID 65540, whereas the Optimizer expects 2 in D:\haofeng\Apache2.2\www\index.php on line 0’这样错误。将zend optimizer卸载后重装，还是一样。网上查资料，说zend optimizer只能解析php5.2.x及以前的版本，查看自己的php环境确实是php5.2.11。
到下午的时候再一次加密的时候，突然看到zend guard加密的时候还要选择php版本，一下子明白了。贴图：
最后提醒一点：zend加密的时候要把电脑当前时间往前调，因为zend加密的文件有限期的限制；
一定要选择准确的php版本，否则zend optimizer无法解析。

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.

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).

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.
