10 recommended articles about object-oriented

Starting from PHP version 5.4.0, PHP provides a new concept of code reuse, which is Trait. Trait literally means "characteristics" and "features". We can understand that using the Trait keyword can add new characteristics to classes in PHP. Anyone who is familiar with object-oriented knows that there are two methods of code reuse commonly used in software development: inheritance and polymorphism. In PHP, only single inheritance can be achieved. Traits avoid this. The following is a comparative explanation through a simple example. 1. Inheritance VS Polymorphism VS Trait now has two classes: Publish.php and Answer.php. To add LOG function to it, record the actions inside the class. There are several options: Inherit polymorphic Trait1.1. Inheritance is as shown in the figure: The code structure is as follows:// Log.php

2. 10 recommended courses about inheritance

Introduction: The content explained in this section is encapsulation, inheritance, polymorphism, overloading and rewriting. Preface: PHP's object-oriented is the same as JAVA's object-oriented, and they are divided into three major characteristics. Encapsulation, inheritance, polymorphism. These three features optimize object-oriented in many aspects. These three characteristics are also issues that need to be considered when developing object-oriented. Encapsulation in object-oriented What is encapsulation? Encapsulation: Encapsulate abstracted data and operations on the data together. The data is protected internally. Other parts of the program can only operate on the data through authorized operations (member methods). Abstraction is mentioned above, that is, a class of things...

4. Java array introductory tutorial: 10 java array zero-based introductory tutorial recommendations

Introduction: Array is a data type that is basically found in all languages. It represents a set of data of the same type. A collection of fixed lengths that occupy contiguous space in memory. In languages ​​such as C and C++, the definition of arrays is concise and clear, but in Java there are indeed some confusing features. This article attempts to analyze these characteristics. Are arrays in Java objects? Java and C++ are both object-oriented languages. When using these languages, we can directly use standard class libraries, or we can use object-oriented features such as composition and inheritance to build our own classes, and build according to our own...

5. Detailed introduction about Tabcontrol

简介：使用JavaScript，按照面向对象的思想来构建组件。现以构建一个TAB组件为例。从功能上讲，组件包括可视部分和逻辑控制部分；从代码结构上讲，组件包括代码部分和资源部分（样式、图片等）。组件的特点：高内聚，低耦合（不与其他代码逻辑交叉，可以继承，包含）；封装性（隐藏私有方法和变量）；可重用性（可反复多次使用，用来组装更复杂的应用）。&l...

8. php有关故障处理的详细介绍

简介：在面向对象的程序中，我曾经见过的最大的switch/case语句所具有的条件超过了20个。在运行期间，这个代码模块每次都要执行所有的条件。每个条件都负责创建一个新的对象，这个对象被用于与应用程序API的外部使用这进行通信。对其中一个执行某些常规的故障处理之后，我开始研究应用程序所实现的接口。令我吃惊的是，switch/case语句中引用的每个类都在实现相同的接口！随后要在switch/case语句...

9. 范围解析函数定义与用法汇总

简介：面向对象编程中会使用到一些它自己的操作符，如->，这个符号用来在对象中访问它自己的成员。另外一个是范围解析操作符：两个冒号连在一起（::）。这个符号用于在类中（而不是对象中）访问成员。使用方式如下：ClassName::methodName();ClassName::propertyName;这种结构在两个地方可能被用到：1.在使用类的时候，父类和子类具有相同的属性和方法时，利用它可以避...
