The ^ operator in the PHP language is often used for encryption operations, and the decryption can also be done directly using ^, but when communicating with other languages, other languages such as objective-c may not be able to parse PHP's ^, especially when php uses multiple strings such as abc ^ def, in other languages, there are few such operations that can

After learning the Python language to learn PHP JavaScript, these programming languages are better able to understand quickly, After having the Python foundation, it is easier to learn the PHP language comprehension. I would like to study the two aspects of PHP JavaScript, my friend suggested that after I learned Python, and then to learn PHP will be easier to understand these programming languages The gre

Guidance:Do developers still need a new programming language? There are already so many choices, and the existing languages are overwhelmed by developers, but various new programming languages are still produced at an astonishing speed! The answer is that with the continuous development of multi-core CPU, cloud computing, mobile and distributed structures, simple syntax is no longer applicable. We need more

First, computer language classification　　Low-level language, high-level language, specialized language, scripting language1, Low-level language : Machine language, assembly language and symbolic languages. Machine language is a kind of machine instruction (machine code) that can be directly recognized and executed by the computer by using the binary code, which is the computer's designer to give the computer's operation function through the computer's

Why writing comments must be a hard-coded standard for coding (bilingual original) Why Writing Annotation must become peremptory Rule? The most annoying thing about a program ape: Someone else's code does not write comments; Parodox:it is the most hated for programmers that others ' code has not annotations, and oneself must write annotations. 1. Comments are mostly for others to see, for their own review is icing on the cake It is quite difficult to

Android is a Linux-centric mobile phone operating platform, as an open-ended operating system, with the rapid development of Android, now allows developers to use a variety of programming languages to develop Android applications, It's no longer a single scenario where you can only use Java to develop Android apps. So, what languages can the Android system use to develop?In Android, developers can use Java

Reply content:Any "XXX language is too slow" concept is to generalize. The application is divided into many kinds, CPU bound, I/O bound, Memory bound, and so on. If your program is an I/O bound, even if you replace the entire program with a manually optimized C, the speed will not be substantially improved. For Dropbox, its business logic is not complex, and performance bottlenecks are obviously in I/O. Except I estimate the heavy SHA operation is relatively large, but the CPython advantage is t

If you are waiting for a ride, we will not continue the development process today. let's talk about background language issues that are commonly concerned. I have been learning ExtJS, and I have always stressed that the central idea of learning is to take a bus between interfaces and wait for a while. today, I will not

1) Java and James GoslingJava is one of the most successful and popular programming languages in the world. Dr. James Gosling invented Java and was honored as the father of Java. Earlier, Java was developed and powered by Sun Microsystems, which is now being completed by Oracle after Sun was acquired by Oracle in January 2010. Java was created to complete the concept of Wora (write once, run anywhere), and its platform independence made it a great suc

Item 1:view C + + as a federation of Languages At first, C + + was just the C language plus some object-oriented features, so C + + 's original was "C with Classes". Now C + + has matured to become a multi-paradigm programming language (Multiparadigm programming language). It also supports programs, object-oriented, functional, generic programming, and meta-programming.The flexibility of C + + makes it not uniform on many issues, but depends on t

Today, I saw the ranking of programming languages announced by tibench in June on CSDN. I suddenly want to know How tibench calculates the ranking of programming languages ?. Open Tianyi's introduction to programming language ranking. The general knowledge is as follows:1st: A language must meet two criteria to enter the ranking: You must have a separate entry on Wikipedia and specify it as a progr

: This article mainly introduces the three programming languages you need to know. if you are interested in PHP tutorials, refer to them. Each programmer must have at least three programming languages. Of course, this is just my family. This is my opinion developed over the years. it may be a bias, but I can quickly understand a programmer based on a person's favorite programming language. When I read my r
