一个让人大吃一惊 的写法

Jun 23, 2016 pm 01:33 PM

Model('seo')->type('index')->show();在一个源码中看到这样的话,这个源码其实是一个mvc框架,不过为啥大吃一惊呢,其中Model其实是一个公共函数,不是一个类中的方法,
而后面的连贯写法,却是类的写法,我查了一下type函数和model函数也没啥关系,也没有查出在逻辑上有啥关联,
但却用了类的写法,不知这里有啥玄机不成


回复讨论(解决方案)

Mode公共方法里面应该是实例化了seo类

这有什么可奇怪的
Model 是一个函数,他会根据传入的参数返回一个对象
比如 Model('seo') 就返回一个与 seo 相关的对象
你只要看看 Model 函数的定义就可以了,他一定有类似这样的代码

function Model($name) {  return new $name;}
Copy after login

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,

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.

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.
