What is the difference between php and nodejs

Difference: 1. PHP is a programming language, and Node.js is a JavaScript running environment. 2. PHP applications can run on any server and are easy to deploy; Node.js requires a virtual server with SSH access. 3. PHP supports more resources for developers to develop than nodejs.

PHP

Rasmus Lerdorf created PHP in 1994. It is run by components installed on the web server (Apache, Ngix). PHP code can be mixed with HTML. Beginners can quickly write valuable code without much practice. This has made PHP become more and more popular, and PHP is now running on 80% of the world's servers. WordPress, a content management system used by a quarter of the world’s websites, is written in PHP.

Node.js

Ryan Dahl created Node.js in 2009. It is based on Google's V8 JavaScript interpretation engine (which is responsible for executing client-side JavaScript code in the Chrome browser). Unlike other languages, Node.js has built-in function libraries for handling network requests and responses, so you don't need a separate server (Apache, Ngix) or other dependencies. Node.js is new but has quickly gained huge popularity. It is used by many large companies, such as Microsoft, Yahoo, LinkedIn and PayPal.

The difference between php and nodejs

1. Essentially different

PHP is A programming language, and Node.js is a JavaScript runtime environment based on the Chrome V8 engine

2, hosting and deployment:

PHP applications can be run on Nginx and Apache and runs on any server including 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 using 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 perform well at high throughput, but when the application is heavy and requires the CPU to do a lot of work, Node.js .js will definitely be lacking. In this case, PHP is best suited for the backend of the web application.

5. Community support:

Since 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.

6. 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 concepts like web workers and callback functions before getting started.

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.
