PHP与Node.js

什么是PHP?

PHP代表超文本预处理器,它是一种开源脚本语言。它是服务器端脚本语言,是用于创建动态和交互式网站的强大工具。

PHP是一种解释型语言,因此不需要编译。它是专门为在服务器上执行的服务器端脚本而设计的。PHP可以轻松地嵌入HTML文件。

注意:PHP主要用于开发服务器端应用程序。

它具有以下优点:

  • 我们可以在Windows,Linux,UNIX,Solaris等不同平台上执行PHP代码。
  • 它易于使用和学习。
  • PHP提供了一个内置模块,可以帮助它轻松地与数据库连接。
  • PHP是一种开源语言,这意味着它是免费提供的。

通常,PHP是廉价,跨平台,快速且可靠的Web开发应用程序。

什么是Node.js?

Node.js是一种在服务器上运行的JavaScript编程语言。它有助于创建动态和交互式的网页。Node.js文件以.js扩展名保存,并且仅包含JavaScript代码。它在浏览器外部执行JavaScript代码。

Node.js是一种开放源代码语言,可在Windows,Linux,UNIX和MacOS等不同环境中执行。

Node.js具有许多优点,在下面列出。

  • Node.js快速且轻量级。
  • 它比PHP更安全。
  • Node.js允许我们为客户端和服务器端编写JavaScript代码。
  • Node.js具有可伸缩性,即,可以轻松地在垂直和水平方向上扩展应用程序。
  • 由于Node.js,JavaScript现在可用于每种浏览器,并且可以在每台服务器上运行。

PHP和Node.js之间的区别

PHP和Node.js都是服务器端脚本语言。因此,他们已经成为彼此的竞争对手。它们必然有一些相似之处,也有一些差异。以下是一些基于其功能和特性的差异。

Features PHP Node.js
Runtime Environment PHP is straightforward to install and use at server-side. PHP is straightforward to install and use at server-side.
Powered by PHP is powered by Zend engine. Node.js is powered by Google’s v8 JavaScript engine.
Execution PHP is synchronous except some APIs. It is totally asynchronous.
Framework PHP has many frameworks for easy backend development, such as Laravel, CakePHP, etc. Node.js also has popular frameworks like Express, Meteor, and DerbyJS, etc.
Execution Speed PHP execution speed is slower than Node.js. Node.js is faster than PHP and lightweight too.
Web Server PHP needs Apache web server to execute the code. Node.js doesn’t need any web server to execute. It runs in its own environment.
Compatibility with other languages PHP can contain HTML, JavaScript, CSS, and even plain text. Node.js can contain only JavaScript.
Used by Facebook, Wikipedia, Yahoo, Flickr, and WordPress, etc., are using PHP. IBM, GoDaddy, NetFlix, LinkedIn, Paypal, and Walmart are the adopters of Ndoe.js.
Complexity PHP is simpler to use than Node.js. Node.js is not too complex, but need more lines of code and callback functions.
Basic syntax echo ‘Hello PHP’; Console.log(‘Hello Node.js’);
Module A developer needs to download and install PHP manually. It doesn’t come in bundled with module. It comes prepackaged with the NPM package management system and its registry.
Performance PHP is fast, but slower than Node.js due to the database, third-party request, and file system. Node.js is faster due to its non-blocking mechanism.
