(-XML- )gbk文本

Jun 23, 2016 pm 01:11 PM

创建一个简单XML结构,源文件用gbk编写结果报错,改成utf8格式就正确,求原因?

//这是出错的gbk编码的文件            header('content-type:application/xml;charset=gbk ');            $x = new DOMDocument('1.0', 'gbk');            $a = $x->createElement('a');            $x->appendChild( $a );                        $you = $x->createTextNode('你');            $a->appendChild( $you );            echo $x->saveXML();
Copy after login

================================下面是不出错的U8编码的源文件=================================
//这是U8编码的源文件             header('content-type:application/xml;charset=utf-8 ');            $x = new DOMDocument('1.0', 'utf-8');            $a = $x->createElement('a');            $x->appendChild( $a );            $you = $x->createTextNode('你');            $a->appendChild( $you );            echo $x->saveXML();
Copy after login

XML 的工作字符集是 utf-8

如果是工作字符集U8的原因,那么参数二可以指定encoding还有什么存在意义呢?另外报错中的conv error是什么错误?

XML 的工作字符集是 utf-8

conv error 转换失败

指定工作字符集,只在微软的部分产品中有效(因为 XML 是微软发明的)

php5.3 以后,可以读取非 utf-8 字符集的 XML 文档

php有没有可以把xml对象按gbk格式输出字串的方法?

conv error 转换失败

指定工作字符集,只在微软的部分产品中有效(因为 XML 是微软发明的)

php5.3 以后,可以读取非 utf-8 字符集的 XML 文档

是我说的不准确

header('content-type:application/xml;charset=gbk');$x = new DOMDocument('1.0', 'gbk');$a = $x->createElement('a');$x->appendChild( $a );             $you = $x->createTextNode(iconv('gbk', 'utf-8', '你'));$a->appendChild( $you );echo $x->saveXML();
Copy after login

你可以看到输出的的确是 gbk 编码的内容
也就是说,是可以输出指定字符集的 XML 文档的

但这并不改变工作字符集是 utf-8 的事实

conv error 是在将内部 utf-8 字符集向指定的输出字符集转换时产生的

$you = $x->createTextNode('你'); 中 gbk 的 你 被当做 utf-8 字符进行处理时,自然要出现错误了

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. 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? 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? 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. 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::). 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? 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)? 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? 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.
