PHP object-oriented programming (oop) learning Notes (1)-abstract classes, object interfaces, instanceof and contractual programming. 1. PHP's abstract class PHP5 supports abstract classes and abstract methods. Classes defined as abstract cannot be instantiated. If at least
a method body, which is similar to an abstract class. The difference between them is that an interface cannot declare any method that has a method body, and they use a different syntax. To force the uncover rule to be added to a class, we need to use the Implements keyword instead of the extends keyword.In some cases we need to determine whether a class is a type of a particular class, or whether a particular interface is implemented. Instanceof is divided into fit to complete this task. Instan
Process-oriented program:
The idea is to program the playing chess process, that is, the low-level, layer-by-layer and accurate programming thought we are usually used. The dominant idea of this programming is to take the implementation details into consideration during the design, so that the program can meet the application software requirements at the lower la

"Real geniuses have the ability to correctly assess uncertain, risky and contradictory information. --Churchill "
When working with many programming languages, you can usually only use one of the object-oriented or process-oriented programming methods.
Short, object-oriented programming is to wrap a class class outside of a function program, and then point the class to an objectAnd the functions in class are called methods here.As an example:Use functional programming to write a script that sends a message in one click:def e_mail (email,message): print (' mail sen

The software development process has not changed much over the years. The main problems that need to be faced during the software development process are: the long development cycle makes it difficult to ensure the correctness of the program, difficult to maintain and so on have not been well solved, despite the emergence of object-oriented, framework design and other concepts and tools. The component

One: What is the programming paradigm?Programming is the process by which programmers use a specific syntax + data structure + algorithm to tell a computer how to perform a task.If the programming process is likened to practicing martial arts, then the programming paradigm refers to the various genres in martial arts,
process-oriented programming
Process-oriented programming is a process-centric programming idea, analyzing the steps to solve the problem, and then using the function to implement these steps step by step. Process-oriented

Because we always use process-oriented programming ideas to write JS Code, and because the network is filled with too many small "clever" JS code segments, many of them are casual and very nonstandard, this leads to a "misunderstanding" of JS, blindly believing that it is an auxiliary little stuff, and not suitable for development of big things. However, since the rise of AJAX, a large number of JS code com
