Node.js vs. PHP: Explained

Node.js vs. PHP: Explained
By Team TIS

Node.js and PHP are both top-notch technologies that are top choices for server-side programming. 

PHP is used for web development since it is a GPL or a general-purpose programming language used by a lot of applications and websites. 

On the other hand, Node.js allows you to build scalable, fast and effective back-end applications. Since it is a runtime environment, it enables developers to run JavaScript on the server side. 

Even though  PHP and Node.js are different, these tools provide similar functionalities since they work in similar technological ecosystems. 

This makes it difficult to choose between them. 

In this blog, we will walk through the differences between PHP and Node.js and help you decide which one to use for your project. 


PHP was initially known as “Personal Home Page”. It was created in 1993 by  Rasmus Lerdorf. It has now evolved into  “PHP: Hypertext Preprocessor” which is a complete programming language in itself. 

Initially, web developers used PHP mainly for the purpose of server-side programming. 

But it quickly became the foundation of web development once it was integrated with other technologies to develop Linux, Apache, MySQL and PHP (LAMP) stack. 

It gained popularity in the blink of an eye, as a software bundle that is an effective open-source platform which is used for development and deployment of interactive and adaptable web-based applications. 

LAMP had a huge influence on web development. It allowed developers to freely collaborate on projects and share code. This boosted the growth of the internet at a lightning fast pace. 

In the present world, PHP is used for everything, ranging from command-line scripting to microservices and web-development. 

More than 70 percent of the total number of existing websites today are built using PHP.


JavaScript was created in 1995 to make websites interactive. It became one of the most popular choices for front-end web development and evolved into a programming language, just like PHP. 

Node.js was introduced by Ryan Dahl in 2009. It was created to support the use of JavaScript on the server-side, this would make it possible to create fast, efficient and scalable back-end applications. 

It is now used by some of the most popular companies such as eBay, Netflix, PayPal, etc. 

This also facilitated developers to use their knowledge of Java Script to create both back and front ends using the same language.

With the evolution of the Node.js ecosystem, development of many powerful JavaScript libraries and frameworks has been made possible, such as, Express.js, etc. 

It has made it much simpler to build complex, high-performance applications. 

Node.js vs PHP

Now that we have gone over the basics, let us see how PHP and Node.js compare to each other in terms of technology, capabilities and functionalities. 

  • Ease of Use:

When developers look at a new technology or language, the first and most important quality they look for is ease of use. 

PHP is a language that is easier for developers with a C-style language background. This is because of its extensive standard library and simple syntax that provide many features and functionalities. 

Node is generally found to be easier to use by developers with a background in JavaScript. 

This is because it is easier to adapt quickly due to its simple syntax and large framework that allow web application building as well. 

  • Performance

Choosing between PHP and Node.js involves considering a few key factors such as performance and how they handle requests.

Let’s think of PHP as a focused artist. It is a synchronous language, which means it prefers to work on one piece at a time. 

The server focuses on one request, sees it through to completion and only after completion moves on to the next one. While this ensures every task gets its due attention, it can become slow and extremely time consuming if there are a ton of requests coming in all at once.

On the other hand, Node.js is more like an expert juggler. It is an asynchronous language and is naturally able to handle multiple requests at the same time. 

When a request comes in, the server quickly passes it on to a worker process and immediately gets ready for the next one. 

It is this ability to process multiple requests all at once that makes Node.js a more efficient choice than PHP when there is a high volume of requests to manage.

  • Community support and Documentation

PHP is somewhat like an open book with an extensive online manual that is filled with detail about syntax, functions, and best practices. 

It also includes examples and explanations that make you understand how to use it in various contexts. 

Also, the PHP community isn’t just limited to the official manual, there are tons of third-party resources and tutorials available online, making it a well-supported language.

Node.js does not lack either. It comes with comprehensive online guides that explain the syntax, modules, and best practices. It also provides a ton of examples and use cases. 

Apart from the official Node.js resources, you will find a plethora of tutorials and open-source materials.

Both PHP and Node.js have a large number of users as well as developers. Platforms like Stack Overflow are filled with activity and are great places to seek help with specific issues or to simply learn more about these languages.

  • Architecture

PHP is a great choice for traditional web applications. It operates using a multi-threaded, blocking architecture, which means each request gets its own separate thread. 

However, this can sometimes end up being slow and time consuming when dealing with huge volumes of data.

On the other hand, Node.js uses a single-threaded, non-blocking architecture, enabling it to manage multiple requests at once without causing any issues with efficiency. 

This makes Node.js a better fit for applications that need high efficiency levels and real-time updates, keeping everything running smoothly even when the pressure is high.

When deciding between PHP and Node.js, consider these differences in architecture to help you choose the one that best suits your project’s needs.

Uses of PHP and Node.js- 

Choosing between PHP and Node.js often comes down to your specific project requirements. Some of the major factors to consider when choosing, are:

  • Security

If your project is dealing with sensitive data and demands high-level security measures, PHP would likely be the go-to. 

Its built-in security features, including output encoding and input sanitization, can safeguard against common web application vulnerabilities. 

This is particularly useful in fields like fintech where user data protection is paramount. 

Plus, PHP’s long-standing history of security updates enhances the ease of maintaining a secure application.
