PHP 框架和模板的区别是什么?
回复内容:
PHP模板一般指的是View层的东西,很少单独拿出来说事,和框架没什么好对比的。 模板引擎倒是会拿来说一下,但也不过只是如何实现View层上代码和表现分离的Library罢了。一般来说,相提并论的是库(Library)和框架(Framework)。 Library通常只是实现了某类功能,而Framework则像管家一样,打点你的几乎整个生活。 比如Smarty就是个Library,而Zend Framework就是个框架。
Smarty只集中解决了代码和表现分离这件事情,类似的PHPExcel、phpGraph、phpMailer等等都是类似的Library。 而框架则往往会包含 MVC(Model - View - Controller,数据 - 表现 - 逻辑三者的分离)、URL路由、多环境支持、多语言支持、输入输出的安全处理(防SQL Inject和XSS之类)、扩展机制、通用分页、常用小功能等等,形成一个项目的基础架构,让开发者将精力集中在具体的实现上,无需为了常用的这些基础设施耗费精力。

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,

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.

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.

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.
