This article mainly introduces how PHP programming can improve programming efficiency (keep these 20 points in mind). If you need to use single quotation marks instead of double quotation marks to include strings, this will be faster. Because PHP will search for variables in strings enclosed by double quotes, but not in single quotes. Note: Only echo can do this, it is a "function" that can treat multiple s

IOS network programming synchronizes GET Method Request programming, and ios network programming synchronizes get The iOS SDK provides two different APIs for synchronous and asynchronous requests for HTTP requests. You can also use GET or POST methods. First, we will understand the simplest synchronous GET request. First, the query service can be implemented in t

Linux Network Programming-original socket programming and linux Network Programming The original socket programming is similar to the previous UDP programming, except that after a socket is created, data is received or sent through the socket. The difference is that,The orig

decryption, compression and decompression, and so on (that is, the computer can recognize things to convert adults can recognize things (such as pictures, sounds, etc.). 7. Application layer: Mainly some terminal applications, such as FTP (a variety of file downloads), the WEB (ie browsing), QQ and so on (it can be understood as we can see on the computer screen things.) is the terminal application). Network applications: Network programming, IO str

mod_deflate module, you can improve the browsing speed of the Web page. 16, the database connection should be turned off when use is finished, do not use long connection. 17. Error messages are costly. 18, in the method to increase the local variable, speed is the fastest. Almost as fast as calling a local variable in a function. 19, incrementing a global variable is twice times slower than incrementing a local variable. 20, incrementing an object property (such as: $this->prop++) is 3 tim

Many JavaScript-oriented programming methods are popular on the market, many of which are problematic. Here's a summary of the most correct JavaScript object-oriented programming patterns. For class Special inheriting from class Common inheriting from class Super, the creation of a Special object, in detail, should go through the following steps. 1 Determining the inheritance Relationship 1.1 Read Special's

, the desktop IP set to 192.168.127.222, and the IP of the notebook is 192.168.137.1, the two are not a network segment at all. After the desktop was changed to 137, the two moxa IP was changed to 192.168.137.252, 192.168.137.201. Successful implementation of the most basic communication. 2, the client's socket in the settings must use the server's IP and port ... Socket programming in the server, the port needs to indicate that IP with inaddr_any (Le

embedded real-time programming With the expanding application scope of embedded system and the extensive use of embedded real-time operating system RTOs (real time operating system), advanced language programming is an inevitable trend of embedded system design. Because the assembly language and the specific microprocessor hardware structure is closely related,

Man invented the programming language in order to control the machine. Computers are becoming more powerful, and programming languages are constantly being innovated. So I boldly believe that the meaning of programming language will be beyond the control of the machine, it may be a starting point of civilization-robot civilization. To better envision the

After more than 50 years of birth, functional programming (functional programming) began to gain more and more attention.Not only did the oldest functional language Lisp regain their youth, but new functional languages such as Erlang, Clojure, Scala, F #, and so on were emerging. Currently the most popular Python, Ruby, Javascript support for functional programming
