The 20 key points for improving PHP programming efficiency and the key points for php programming efficiency. 20 key points for improving PHP programming efficiency. the key points for php programming efficiency are to replace double quotation marks with single quotes to include strings, which is faster. Because PHP se

When it comes to aspect-oriented programming, we can easily relate to object-oriented programming (OOP). The explanation for these two types of programming is that the two programming ideas are just the point of view of programming.OOP focuses on the object, how the object behaves and how it is abstracted. How to encap

OverviewUDP is a non-connected, unreliable datagram protocol, and any reliable transmission needs to be provided by the application, such as: time-out retransmission, serial number response mechanism, but it is efficient and convenient to use in some situations. It supports broadcast and multicast. The basic UDP socket programming reference to this article, this is only on that basis, to record some of the problems in the UDP

The "UDP protocol" and "Socket data transfer" are described in the previous article. The UDP protocol differs from the TCP protocol in that it is a non-connected, unreliable transport layer protocol. In UDP socket-based programming, data transfer is available in functions SendTo and recvfrom. The following is the basic UDP socket programming Process:SendTo and Recvfrom functionsThe functions are similar to

Yui3's AOP (Aspect-Oriented Programming), OOP (Object-Oriented Programming), and yui3aop First, put your hands in front of your chest to become a meditation: I went to life, or I was living myself? I didn't come up with the answer. Well, I can read the following. From a semantic perspective, different expressions of the same thing can reflect the different subjective perspectives of people. From a philosoph

Customer-Server programming method and Client Server programmingCustomer-Server programming method The Client Server programming method is thoroughly described in the first volume of unix network programming. This article omitted the coding details and presented them through pseudocode. It mainly introduces the ideas o

Awk programming model and awk Programming It is important to understand the basic model that awk provides to programmers. Learning awk is easier than learning other programming languages because awk provides programmers with well-defined and useful models. The awk program is composed of a so-called main input loop. A loop is a routine that repeats until some co

Declarative Programming is a simpler and more refined way to describe the behavior of a software program. It means that you can define the behavior of a program by declaring, rather than using instructions. In C #, most programming is imperative, that is, defining the behavior of a program by writing methods. We can use features to implement Declarative Programming
