##判断中文的原理
注意: 中文与汉字CJKV 的区别。。日本,韩国,新加坡,古越南等国家也用汉字,但不是中文。。就像英文法文都使用拉丁字母,但拉丁语不等于英文。。
汉字Unicode区间4E00(19968)? 9FBF(40895) ,表意文字的区间,包括了多个国家的汉字,这个不是我们所需要的。。
GB
中文中的汉字又分为简体,繁体,3500常用字,而同是繁体汉字,香港--澳门--台湾--海外等地方使用的汉字也有一些区别。。同是简体汉字,中国大陆--马来西亚--新加坡--海外等地方使用的是有一些差别的。。
一般我们只需要的是大陆地区3500常用简体中文汉字(gb2312)。。
2312标准共收录6763个汉字,其中一级汉字3755个,二级汉字3008个;同时收录了包括拉丁字母、希腊字母、日文平假名及片假名字母、俄语西里尔字母在内的682个字符
3500常用文字在unicode编码中不是全部连续的。无法用一个正则来写出这个区间。

只能使用map装载这个3500汉字映射,再对输入文字进行配对判断。

##判断汉字的原理
相对于判断中文,判断汉字就方便多了。
汉字Unicode区间4E00(19968)? 9FBF(40895) ,表意文字的区间,包括了多个国家的汉字
取得汉字的acii/unicode码
在判断大小走ok兰..



##uapi
获得汉字unicode 编码...  unicode()
判断汉字(所有国家地区)  isChinesChar()
判断中文(大陆)汉字 isChinaChineseChar()
判断日文汉字 isJapanChineseChar()
判断韩文汉字  isKoreaChineseChar()

##java

char word1 = 'Y';
(int) word

##php  PHP ord() 函数

##python
def isChinesChar(char):
    """"
    汉字Unicode区间4E00(19968)? 9FBF(40895)
    '('括号ylei的yanen fenkail ,bs chchar.. 
    """
    unicodex=ord(char)
    if( unicodex>=19968 and unicodex      
        return True
    else:
        return False

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.

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.

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.

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.
