如何评价“约定优于配置”的编程模式?

这是框架的设计理念,没见过哪个语言是这样的。 语言的语法就可以看做是一种约定
编译器或解释器的参数如果能影响语法的含义或支持,就算配置。 用心智空间换打字速度 人都是很懒的,能既省时间又省精力干嘛要重复做那些麻烦的事 我想到了lavavel,你倒是举个例子啊~~ 作为一个可悲的java开发者,我说一下感性的东西。
多组件配合的时候,你可以去配置,100个配置点你就有写100遍,因为你不可能知道这些配置点默认值是什么,是否必填项。
那么,约定就好像java的getter和setter,name属性,它的setter必然是setName,getter必然是getName,我不需要去配置中指定,用反射直接可以拿到setName和getName。
这是一种设计理念,一个团队中约定条件1 2 3,比如,dao的底层sql查询用add_表示增、del_开头表示删除,那么配置事务时候就直接add_* 指定一个策略就行了,这是约定。减少你出错的可能性,这是工程层面的东西,那么扩展到一种语言,就好像java的getter和setter,也算一种约定,但是为了语言的灵活性,这样的约定会比较少,不像框架中约定使用的这么随意。 就好像和熟人合作优于陌生人,但现实是残酷的 约定重于配置会造成熟的人上手很快,不熟的人学习成本上升。
约定重于配置会导致扩展性下降,为了弥补配置的不足会产生很重的实现,最终又体现在学习成本的增加上。
约定重于配置能够让熟手在熟悉的领域快速开发,长远来看不一定是好事。 约定大于配置,只要记住约定的,就少写了配置文件 没见过哪个语言?go语言的函数首字母大写表示public、小写表示private算不算?

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.

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.
