Can NodeJs realize all the functions of PHP?

NodeJs can realize all the functions of PHP. Essentially, all languages ​​can realize all the functions of PHP. NodeJs is a platform based on the Chrome JavaScript runtime, which means that JavaScript can be run on the server side. .

NodeJs Features

The V8 engine itself uses some of the latest compilation technologies. This greatly improves the running speed of code written in scripting languages ​​​​such as Javascript and saves development costs. Demanding performance is a key factor in Node. Javascript is an event-driven language, and Node takes advantage of this to write a highly scalable server. Node uses an architecture called an "event loop" to make writing highly scalable servers easy and safe. There are a variety of techniques for improving server performance. Node has chosen an architecture that can both improve performance and reduce development complexity. This is a very important feature. Concurrent programming is often complex and full of landmines. Node bypasses these but still provides great performance.

Node uses a series of "non-blocking" libraries to support the event loop. Essentially, it provides interfaces for resources such as file systems and databases. When sending a request to the file system, there is no need to wait for the hard disk (to address and retrieve the file). The non-blocking interface will notify Node when the hard disk is ready. This model simplifies access to slow resources in a scalable way that is intuitive and easy to understand. Especially for users who are familiar with DOM events such as onmouseover and onclick, they will feel familiar.

Although letting Javascript run on the server side is not a unique feature of Node, it is one of its powerful features. We have to admit that the browser environment limits our freedom to choose programming languages. Any desire to share code between servers and increasingly complex browser client applications can only be achieved through Javascript. Although there are other platforms that support Javascript running on the server side, Node has developed rapidly and become the de facto platform because of the above characteristics.

In the short time since Node was launched, the community has contributed a large number of extension libraries (modules). Many of them are drivers for connecting to databases or other software, but many of them are very useful software produced by their capabilities.

Finally, I have to mention the Node community. Although the Node project is still very young, it is rare to see such a passionate community for a project. Whether you are a novice or an expert, everyone uses and contributes their abilities around the project, and is committed to creating a paradise for exploration, support, sharing, and listening to suggestions.

Advantages of Node

As an emerging front-end framework and back-end language, Node has many attractive features:

RESTful API

Single-threaded

Node can still process tasks concurrently without adding additional threads - Node.js is single-threaded. It implements concurrent operations through the event loop, and we should make full use of this - avoid blocking operations as much as possible, and instead use non-blocking operations.

Non-blocking IO

V8 virtual machine

Event-driven
