PHP 中htmlentities函数的运用
PHP 中htmlentities函数的使用
对于htmlentities这个函数我是这么理解的，由于直接输入一些字符，浏览器不认识，所以会出现乱码，所以要用这个函数把一些字符转换成浏览器能认识的实体。不知这么理解对不对。
我这里看到一个例子
echo htmlentities("Coffee at Cafè Francaise costs $2.25.");
说由于è这个字符浏览器不认识，所以直接输出的话，会是乱码，所以要用htmlentities来转换一下。
可问题是我试了一下echo "Coffee at Cafè Francaise costs $2.25."; 也能正确的输出那个è。
请问这是什么原因？那我们还需要htmlentities吗？

你教英国人说英语，显然就是班门弄斧了
但你教法国人说英语，却又是很平常的了
用的浏览器能认得“è”，那是他的母语。有的浏览器不认得“è”，你却又不能将它枪毙掉。怎么办呢？弄个世界语告诉他

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,
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.
