Serialization serialization formatIn PHP, serialization is used to store or pass the value of PHP without losing its type and structure.The serialization function prototype is as follows:serialize($value)Let's look at the following example:class CC{

Abstract classIn any class, if at least one method inside a class is declared abstract, then the class must be declared abstract, and the method defined in the abstract class as abstract can only be invoked in a declarative way, but not in a

1, RTTI:run-time type information allows you to discover and use type information while the program is running. There are two ways to identify objects and classes at runtime in Java: Traditional Rtti, and reflection. Here is the next rtti. RTTI:

Copy Code code as follows: /** * Intermediary mode * * Use a Mediation object to encapsulate a series of object interactions so that the objects do not need to be explicitly referenced to each other so that they are loosely coupled and can

Asp.net|web|web Services | creating | Designing a simple XML Web service using ASP.net is relatively easy, however, the real power of XML Web services can only be realized when you have studied the infrastructure. XML Web services are built on the.

Why do I need to design abstract classes? In actual development, there may be a class that is the parent of other classes, but it does not need to be instantiated in itself, and the primary purpose is to allow subclasses to inherit. This can

In C #, the overload of the virtual method has some experience, now share with you. First of all, please take a look at the following example, Using System; Abstract public class contacts { Public virtual string Prinf () { Return ("This is a

Get started and transition to PHP7 instead of fatal error engine exceptionsThe original link of the park learningParking Code Show videoSince PHP 4, the error handling of PHP has been almost static. Just add the e_strict in PHP 5.0, add the

abstract classes and InterfacesI. Abstract classes and abstract methodsFor abstract classes, you first need to introduce abstract methods, and abstract classes exist because of the existence of abstract methods 1. Abstract method (1)

Easy access to the php design mode and easy access to the design mode Problems solved by visitor Mode In our code writing process, we often need to add some code to some similar objects. Let's take the components of printing a computer object as an

  1: Abstract METHODS must not be implemented and must be implemented by an inherited class (if this class is not an abstract class. The class that declares the abstract method must be the abstract class, and the abstract class can have other

Design Mode-proxy, design mode proxy The proxy mode provides a proxy for other objects to control access to this object. In some cases, a customer does not want to directly reference another object, and the proxy object can play a mediation role

The two most common design modes of PHP are factory mode and Singleton mode. 1. the main function of the factory model is to reduce the coupling degree. Copy the code as follows: abstractclassOperation {abstractpublicfunctiongetValue ($ num1, $ num2)

Understand and use the [Translation] of polymorphism in PHP. What is polymorphism? Polymorphism (Polymorphism) is a very long word, but it represents a very simple concept. Polymorphism describes the differences in classes in object-oriented

Note: This tutorial is all taken from the lab building. [16 PHP design patterns]: describes the basic concepts and technical points of 16 common design patterns, the UML class diagram helps you understand the associations between classes in the

The Trait feature of PHP5.4 is a new feature in PHP5.4 and a solution for PHP multi-inheritance. For example, it is very troublesome to inherit two Abstract classes at the same time. Trait is designed to solve this problem. Easy to use First, of
