What are the differences between node.js and php?

Difference: 1. PHP is a programming language, and Node.js is a JavaScript running environment based on the Chrome V8 engine; 2. Node.js follows an event-driven non-blocking I/O model, and PHP follows a Blocking model; 3. PHP applications can run on any server, Node cannot.

Node.js is a JavaScript runtime environment based on the Chrome V8 engine. Node.js uses an event-driven, non-blocking I/O model. [Video tutorial recommendation: nodejs tutorial]

Node is a development platform that allows JavaScript to run on the server side. It allows JavaScript to be on an equal footing with server-side languages ​​such as PHP, Python, Perl, and Ruby. Scripting language. Released in May 2009 and developed by Ryan Dahl, it essentially encapsulates the Chrome V8 engine.

PHP is "Hypertext Preprocessor" and is a general open source scripting language. PHP is a scripting language executed on the server side. It is similar to C language and is a commonly used website programming language. PHP's unique syntax mixes C, Java, Perl, and PHP's own syntax. It is conducive to learning and widely used. It is mainly suitable for the field of web development. [Recommended: "PHP Video Tutorial"]

The basic difference between PHP and Node.js is that PHP is a programming language, and Node.js is a JavaScript running environment based on the Chrome V8 engine. . The following article will give you a detailed introduction to the differences between node.js and php.

The difference between node.js and php

1. Performance:

Because Node.js follows the event-driven non-blocking I/O model , Node.js is able to handle a large number of server requests compared to traditional backend technologies. PHP follows a blocking model where multiple threads are created on the server side to handle multiple client requests, which can lead to high server load and response time if the code is not optimized.

2. Hosting and Deployment:

PHP applications can run on any server including Nginx and Apache as well as Windows and Linux platforms, which makes the deployment process easier.

With Node.js, a virtual server with SSH access is required. Therefore, it would be better to deploy small business and personal applications with PHP without any knowledge of console commands and Secure Shell (SSH).

3. External dependencies:

Node.js has fewer dependencies, and you can set up a web server with just a few lines of code. But to run PHP applications, external server software is required. Developers working with Node.js only need NPM (Node Package Manager) to download Node modules, which can be easily integrated into applications to provide additional functionality.

4. CPU scaling tasks:

Node.js may excel at high throughput, but when the application is heavy and requires the CPU to do a lot of work, Node.js will definitely suffer. lacking. In this case, PHP is best suited for the backend of the web application.

5. Single Page Application:

If you have used Gmail, then you may know what a Single Page Application is. A specific portion of a web page that a web application loads on an initial client request and then refreshes based on the client request. The combination of Node.js and AngularJS is a perfect solution for developing single-page applications.

6. Development environment:

Node.js can be used for desktop application development (Windows, Linux and Mac), mobile application development (hybrid and cross-platform applications), and even building Console based application. While some can also develop using PHP, most developers don't.

7. Community support:

Because PHP was born nearly 20 years earlier than Node.js, it has richer online resources such as documentation, APIs and code libraries. So there's a good chance that someone else has also tried what you're trying to accomplish with code and gotten help.

On the other hand, although Node.js has received widespread attention from developers and organizations, it lacks resources to support developer development.

8. Learning curve:

Writing Node.js code is not an easy task for novices or even professional JavaScript developers, because they need to understand some complex things before getting started. Concepts such as web workers and callback functions.

On the contrary, PHP is a very user-friendly programming language for newcomers to developing web applications.

Node.js and PHP complement each other as both technologies have their own advantages and disadvantages. This is mostly a similar situation when comparing or choosing other technologies for web, desktop and mobile development. Node.js has a future and will definitely occupy a part of the PHP market, but it cannot completely replace PHP.
