PHP and Node.js are both the most popular web technologies today. Both can build complex and large-scale applications, but PHP and Node.js are completely different in design thought and structure.
1. Introduction
PHP
PHP – is an open source scripting language used to create web applications that run on the server. PHP was created by Rasmus Lerdorf in 1994, since then PHP is the choice for management systems like WordPress, Drupal and Joomla. According to the latest statistics in 2019, more than 80% of websites in the world are built with PHP
Node.Js
Node.Js is a platform that runs on V8 JavaScript runtime environment, helping to build web applications in a simple and easy way. Node.Js was developed by Ryan Dahl in 2009, the latest stable version is 10.15.3. Node.Js allows asynchronous programming, so the performance of Node.Js is very respectable. However, at present the popularity of Nodejs is relatively low (only 0.4%), in the future Nodejs will be more popular for developers.
Synchronous processing : perform tasks in an established order. The following job begins to execute only when the first job is completed
Handling asynchronously : perform many jobs at the same time. This method is very common in Nodejs applications.
2. Differences between Node.Js and PHP
Environment
Although both Javascript and PHP can be embedded directly into HTML code, both require interpreters to run.
PHP is used on the server side and is provided by the Zend engine.
Node.Js is run on runtime environment, powered by Google V8 Javascript engine.
Package manager
PHP uses module installation technologies such as PEAR or Composer (frameworks and PHP component packages).
Node.Js comes with a package management system called NPM (Node Package Manager) .
Ability of extension
PHP is supported on most popular content management systems such as WordPress, Drupal, Joomla. PHP is often chosen for small-scale blog, e-commerce websites. In contrast, Node.Js effectively responds to multiple simultaneous operations (I / O operations).
Web server
PHP is run on the Apache server. PHP is also run on the IIS server on the Windows operating system.
Node.js doesn’t need a web server, Node runs on the NPM runtime environment itself.
Efficiency
Although Node.Js is always rated as highly efficient because of the use of the asynchronous model, PHP is also gradually developing in this direction. With libraries like ReactPHP, PHP can also be used in event-driven programming 
However, when comparing Node.Js and PHP environments, you will see that Node.js is much faster than PHP due to a few reasons:
Friendly V8 engine in the browser
- Handling asynchronously
- Use the callback function
3. Conclusion
Thus, through this article we notice the difference between the two most popular web technologies today, Nodejs and PHP. Both have their own advantages and disadvantages, choosing between these two technologies will depend on the projects you do.
No programming language is the best, you are the best
