什么是RESTful？

RESTFUL是一种网络应用程序的设计风格和开发方式，基于HTTP，可以使用XML格式定义或JSON格式定义。RESTFUL适用于移动互联网厂商作为业务使能接口的场景，实现第三方OTT调用移动网络资源的功能，动作类型为新增、变更、删除所调用资源。

本质：是一种软件架构风格

核心：面向资源设置api

RESTFUL特点包括：

1、每一个URI代表1种资源；

2、客户端使用GET、POST、PUT、DELETE4个表示操作方式的动词对服务端资源进行操作：GET用来获取资源，POST用来新建资源（也可以用于更新资源），PUT用来更新资源，DELETE用来删除资源；

3、通过操作资源的表现形式来操作资源；

4、资源的表现形式是XML或者HTML；

5、客户端与服务端之间的交互在请求之间是无状态的，从客户端到服务端的每个请求都必须包含理解请求所必需的信息。

为什么要使用Restful？

解决问题：降低开发的复杂性；提高系统的可伸缩性

Restful与其他架构有什么区别？

soap webserver 是一种跨编程语言，跨操作平台的远程调用技术。通过http协议发送请求和接收结果时采用xml格式封装，并增加了一些特定的http消息头，这些特定的http消息头和xml内容格式就是soap协议

这俩个架构的区别在：1、效率2、易用性3、安全性

效率和易用性：

soap案例：由于soap添加的是特定的http消息头，如果业务提供方（微信）不提供文档...没有人会使用它的api

安全性：

Restful适用于效率要求很高，但安全性要求不高的场景

soap的成熟性对于安全性要求较高的接口设计带来便利

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
