Web development is a diverse and ever-changing landscape. New tools and technologies are emerging regularly, making developers face a dilemma: whether to choose long-standing and mature solutions or to give newcomers a try. In this article, we will talk about the key features and differences between PHP and Node.js for server-side development.
What to Choose: Node.js or PHP?
Why did the situation change? This happened because JS represented by a new Node.js started entering a server-side sphere and distract back-end developers from old-fashioned PHP.

Why do we compare Node.js vs. PHP? The main reason is that they are both open-source and web-oriented. Let’s take a look at their definitions and brief technical overviews.
The PHP Overview
PHP is an interpreted server-side programing language created for web development by Rasmus Lerdorf in 1994. It is processed by an interpreter that is installed as a module in Apache or Nginx web servers. This language is used to write server-side apps and to connect with databases.
The language has a declarative style of writing code. This means that programmers have no limitations regarding the arrangement of code and its structure. PHP syntax is simple, which is why beginners often choose to use it.
The community provides colossal support in solving any kind of problems worldwide. There are lots of sites and web applications based on servers or engines written in PHP.
Initially, PHP was developed as a preprocessor for hypertext pages. Now, it can be easily integrated with HTML, which promotes the popularity of the language. Currently, more than 80% of web servers in the world use this server language.
It is easy to use because of the following features:
- Easy code
- Simple configuration of the development environment
- Wide support of hosting service s
- A powerful code base
- Ability to support many frameworks and CMS (WordPress, Joomla, Drupal, Laravel, Symfony)
- A large library of instructions and FAQs
- A massive community
- Portability (can be run on almost any server and platform)
- Inefficient separation of concerns. PHP doesn’t separate views and business logic. As a result, the code maintainability and scalability is poor, and it’s often hard to introduce new functions and manage large code bases.
- Outdated client-server model. Every page request goes through specific stages, making PHP slower. The tool Memcached can solve this problem, but this is not a standard feature of the language.

The Node.js Overview
The main advantage of Node.js is the npmjs package manager that accelerates software creation. The V8 engine eliminates issues with garbage collection, slow compilation and cache cleaning.
Node.js is often used to create APIs using popular tools such as the Express.js framework for the server, the MongoDB database management system and the Angular.js frontend framework.
One of the main Node.js advantages over PHP is multithreading. It means that apps run permanently, need to initiate only once, and can perform asynchronous tasks. There are other advantages as well:
- Built-in server support
- A single syntax for both the front-end and the back-end, which improves the maintainability of the app and reusability of the code
- Easy to learn, as it’s almost identical to JS
- Excellent for working with large files
- Flexibility as there are few strict rules and dependencies
- More complicated code
- Not well-suited for processing graphics, audio and video Lack of maturity
Comparison of Node.js and PHP
Now let’s take a look at the comparison of two technologies based on some key parameters.
Node.js vs. PHP Performance
PHP provides more reliable and stable performance for various projects. However, when comparing Node and PHP, the former runs faster. This is possible due to the following features:
- The shorter request processing chain
- Fast V8 engine
- Continuous server connections
- Callback function s that process multiple requests at once
Development and Deployment
Coding in PHP for most developers is simple and fast. There is no need for various compilers or converters. You simply write your code in Notepad and can already execute it. The language easily establishes a connection to SQL databases and has no hosting restrictions. If you need to complete a project quickly, then PHP will be an excellent tool.
With Node.js, everything is more complicated. Deploying applications and frameworks requires a complex server infrastructure and preparation.
The PHP code is concise.
In Node, the code for the same output is significantly longer.
PHP works perfectly with the MySQL database and supports various versions of databases such as MariaDB and Postgresql. Your code can work with all databases regardless of the utilized engines.
This is what a connection to a database looks like in both technologies.
Again, the first code appears simpler.
PHP is supported by all hosting services. Therefore, their integration and deployment are easier for small companies or individuals.
Node has fewer hosting services and requires a virtual server with SSH access to run applications.

РНР is generally web-oriented.
Node.js has a wide range of applications: web apps, multithreaded apps, microservices architecture, browsers, microcomputers, microcontrollers and game servers.
PHP is constantly developing and updating. The team introduces new features and concepts to provide maximum execution speed.
Node.js is also actively developing, but there is one difference. The platform contains all modern functions in one main distribution, so there is no such fragmentation. This is a big plus because developers do not have to waste time on reworking the code.
It is quite difficult to choose a winner in PHP or Node.js on the basis of their features and advantages. It would be better to build different test cases for them and carry them out against a benchmark on the same machine. This way you’ll see how they perform in equal conditions and will be able to choose the best option for your project.
When Should You Use PHP or Node.js?
In spite of all the advantages and disadvantages, there’s still no ubiquitous answer as to the best solution. The technology for each backend project should be chosen individually on the basis of its specific features.
Choose PHP if your project includes:
- CMS such as WordPress, Drupal, Joomla, etc.
- Servers such as MySQL, SQL, MariaDB, Oracle, Sybase, Postgresql, etc.
- Solution stacks such as LAMP (Linux, Apache, MySQL, PHP)
Choose Node.js if your project includes:
- Streaming data transfer
- Real-time web development
- Software stacks like MEAN (mongoDB, Express.js, Angular.js, Node.js)
- Built-in expansion capabilities (cluster package)
In this article, we compared PHP vs. Node.js and discovered that these are both great platforms for developing sites and web applications. Naturally, they are both good in their own way, and they also have a few pitfalls. In some situations, PHP is more competitive, while in others — Node is better.
Hopefully, it has become more clear to you how to determine the best option for your company. Of course, you should take into account your personal preferences, as well as the needs, experience and proficiency of your team.
