$_REQUEST为什么是空的？
我的 php.ini 是这样设置的：
variables_order = "EGPCS"
request_order =
request_order 留空的话不是会使用 variables_order 的值吗？
回复讨论(解决方案)
不知道你怎么请求的，把你的请求过程描述一下。
request_order =GP
不是默认的get和post，设置为空干嘛？

xxx.php?aaa=bbb
request_order 为空的时候 $_REQUEST 是空数组，
request_order = "GP" 的时候 $_REQUEST 才有内容。

这就对了，看request_order 的解释，它设置的是$_REQUEST变量的设置和覆盖顺序。如果为空，也就是$_REQUEST不包含P(Post),G(Get)和C(Cookie)变量了，自然就是空了

那 php 的下面这句话是什么意思：
If this directive is not set, variables_order is used for $_REQUEST contents.
不是说留空就会使用 variables_order 的值吗？
还有 php.ini 里面说的 ：
626 ; This directive determines which super global data (G,P,C,E & S) should 627 ; be registered into the super global array REQUEST. If so, it also determines 628 ; the order in which that data is registered. The values for this directive are 629 ; specified in the same manner as the variables_order directive, EXCEPT one. 630 ; Leaving this value empty will cause PHP to use the value set in the 631 ; variables_order directive. It does not mean it will leave the super globals 632 ; array REQUEST empty. 633 ; Default Value: None 634 ; Development Value: "GP" 635 ; Production Value: "GP" 636 ; http://php.net/request-order 637 request_order = "GP"
难道我理解错了吗？我的英文水平是比较差。。。

刚测试了。variables_order = "GP"
或者variables_order = "GPCS"
request_order =
的情况下确实如手册所说,request_order的值会使用variables_order的值。
php 5.2.17.
比较纳闷的是，记得changelog中request_order是在5.3中引入的，不知为何5.2的配置中也有该配置项

但是我用外国的服务器 php 5.3.24 和本地的 php 5.4.4 测试的结果都是 request_order 留空并不会使用 variables_order 的值，而是直接把 $_REQUEST 留空了。
request_order 的确是 5.3 才引进的，会不会是你设置的 request_order 压根没起作用？5.3之前可能 $_REQUEST 直接就使用的 variables_order。
对于 $_REQUEST 的处理，php5.3 的早期版本是有问题的
至少在 php 5.3.6 中，如果没有传入数据，则 $_REQUEST 是未定义的，而不是仅仅为空
不太清楚这个问题是在哪个版本中被纠正的
It does not mean it will leave the super globals array REQUEST empty.

我测试的两个版本是空数组，不是未定义，
刚刚看了 ChangeLog 也没有提到这个，照这么说php文档和php.ini上面说的都是有错误的咯？

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. 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.
What are Enumerations (Enums) in PHP 8.1?
Apr 03, 2025 am 12:05 AM
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.
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
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.
Explain late static binding in PHP (static::).
Apr 03, 2025 am 12:04 AM
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.
What is REST API design principles?
Apr 04, 2025 am 12:01 AM
RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.
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.
What are anonymous classes in PHP and when might you use them?
Apr 04, 2025 am 12:02 AM
The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
