PHP中一个文档中没有的特色[转自奥索]

class oop pear

PHP中的面向对象功能支持 C++ 式的 :: 运算符号!!!
//孤狼:这个::在PEAR中可是频频出现,第一次见的时候搞的我莫名其妙 :)

这个特色文档没有任何说明,但是却有着很好的使用价值。

举一个简单的例子:
比如你以前有很多收集的函数库,你想转向 OOP 方式编程,但是还不能做到完全的封装。 这个特色提供你一个OOP风格的实现。

你定义一个 Util 类:

class Util {
//将所有的函数剪辑到这里
//这个类可以没有任何成员函数
}

然后在你原先使用函数的地方,比如 someFunction(), 修改成:
Util::someFunction(). 这对你需要封装,但是不需要任何成员函数非常有用。

How SpringBoot encrypts and protects class files through custom classloader How SpringBoot encrypts and protects class files through custom classloader May 11, 2023 pm 09:07 PM

Background Recently, key business codes have been encrypted for the company framework to prevent the engineering code from being easily restored through decompilation tools such as jd-gui. The configuration and use of the related obfuscation scheme are relatively complex and there are many problems for the springboot project, so the class files are encrypted and then passed The custom classloder is decrypted and loaded. This solution is not absolutely safe. It only increases the difficulty of decompilation. It prevents gentlemen but not villains.

What is object-oriented programming? Object-oriented programming (OOP) is a programming paradigm that abstracts real-world entities into classes and uses objects to represent these entities. Classes define the properties and behavior of objects, and objects instantiate classes. The main advantage of OOP is that it makes code easier to understand, maintain and reuse. Basic Concepts of OOP The main concepts of OOP include classes, objects, properties and methods. A class is the blueprint of an object, which defines its properties and behavior. An object is an instance of a class and has all the properties and behaviors of the class. Properties are characteristics of an object that can store data. Methods are functions of an object that can operate on the object's data. Advantages of OOP The main advantages of OOP include: Reusability: OOP can make the code more
