PHP Similarities and Differences Ruby ON Rails, Python
Like we say language is the only difference, programming languages also have variations ranging from popularity, usability and reliability. Each language has different uses. The main similarity between PHP, Ruby on Rails and Python is that they are all dynamic object-oriented languages. The superficial level difference is between the Python and Ruby programming languages. Ruby on Rails is a framework for creating web applications in the Ruby language. In this article, I will describe the similarities and differences between PHP, Rails and Python in various aspects of Ruby. PHP PHP (Hypertext Preprocessor created by Rasmus Lerdorf) is a server-side scripting language for the development of dynamic websites. PHP works with databases, sends and receives cookies, evaluates form data sent from the browser, and builds interactive web pages. PHP runs on the same computer, accessing all information and files on the machine and building custom HTML pages to send to the browser. You can have PHP scripts run without a server or browser. PHP code can be included in HTML by using delimiters. PHP is not only for developing web based applications but also for creating desktop applications with graphical user interface (GUI) client applications like PHP-GTK which extends PHP using…
Detailed analysis of sample codes for performance comparison of golang, python, php, c++, c, java, and Nodejs
This article mainly introduces relevant information on the performance comparison of golang, python, php, c++, c, java, and Nodejs. Friends in need can refer to it When I was working in PHP/C++/Go/Py, I suddenly encountered I had an idea and wanted to make a simple comparison of the performance of the recent mainstream programming languages. As for how to compare, I still have to use the magical Fibonacci algorithm. Maybe it’s more commonly used or fun. Okay, talk is cheap, show me your code! Open your Mac, click on Clion and start coding! 1. Why is Go the first one? Because I am using it personally recently and I feel very good. package main import “fmt” func main(){ fmt.Println(fibonacci(34)) } func fibonacci(i int) int{ if(i<2){ return i; } return fibonacci(i-2) + fibonacci(i-1); } Let’s take a look with Go1.7 first: The code is as follows: qiangjian@ localhost:/works/learnCPP$ go version && time go build fib.go && time ./fibgo version go1.7.5 darwin/amd64 real 0m0.206suser 0m0.165ssys 0m0.059s real 0m0.052suser 0m0.045ssys 0m0.004s Then, look at 1.8: The code is as follows: qiangjian@localhost:/works/learnCPP$ go18 version && time go18 build fib.go && time ./fibgo version go1.8 darwin/amd64 real 0m0.204suser 0m0.153ssys 0m0.062s real 0m0.051suser 0m0.045ssys 0m0.003s I…

Comparison of php, python, ruby–web scripting languages
Abstract Scripting languages have become increasingly popular in web application programming over the past few years. This paper attempts to find the differences, advantages, and disadvantages among the three most popular languages today: PHP, Python, and Ruby. Obviously they have their own opinions and support, so stating objective facts and satisfying a scientific approach is a difficult task. The three languages will be evaluated in the context of web applications regarding history, evolution, popularity, syntax, semantics, functionality, security, and performance. Finally, a final conclusion will suggest the most promising language. 1. Introduction Dynamic script programming language has reached the mainstream market as a common programming language. They have certain properties that distinguish them from classic static languages such as C++: — They are dynamically typed — They focus on syntax — They have an automatic memory management and garbage collection — They are mostly interpretive (rather than compiled) These properties are attractive for web application development because they enable rapid prototyping, rapid code changes, and test cases Procedure. There are also differences in the value of specific languages depending on the specific language chosen. However, this article is not about comparing dynamic and static languages, but rather a comparison between…
If you want to learn back-end development, be it PHP, Python, node.js, or… Currently doing Android development. ?
Reply content: By language popularity: php > python > nodejsphp mainstream companies: facebook, Sina, webpage, Sohu, Baidu, Tencent…python mainstream companies: quora, Douban, Zhihu, Guoke… nodejs has fewer well-known sites in China than before. The development language chosen by a startup company is largely affected by the proficiency of their existing employees in each language or the technology used by similar companies. For individuals, let me teach you a way. First establish a target company, and then learn the technologies needed by the company according to its requirements. You can directly read its recruitment brochure. For example, if you want to join a company like Zhihu, you can focus on Python. If there is no target company, simply give priority to the most mainstream PHP, so that you will have more choices when looking for a job. Or first have a general understanding of these three technologies, and then choose the best based on favorability or interest. Of course, if you have a relevant technical background, you can also consider the different learning costs. Depends on your needs. If it is not a particularly large project or you pay special attention to performance. Consider using rails for development. Many foreign start-up…
