Any website or web application is powered by a technology stack that consists of a few virtual layers, including backend and frontend. While the frontend refers to everything that a user sees and interacts with (i.e. user interface: buttons, panels, sliders, etc.), the backend is a set of mechanisms that run under the hood of a project and are invisible to users, such as server-side applications and database queries. PHP and Node.js are technologies used in backend development; thus, they are vital for the fast and efficient performance of a project. It doesn't matter how well-designed and responsive the UI of your project is while the rest of the user experience is laggy and full of errors because of the poorly built backend.
Proficient backend programmers and project managers surely understand how Node.js vs PHP are compared and what strengths and limitations they carry, but if you're a novice to backend development, check this article to learn about the subject. We’ll guide you through the feature comparison of these technologies and help you make your own decision on the Node.js vs PHP dilemma.
PHP is one of the most popular back-end scripting languages out there, originally released in 1994, the abbreviation then stood for Personal Home Page, and is now deciphered as Hypertext Preprocessor. It’s an open-source programming language utilized in WordPress, the top content management system, and other popular CMSs (i.e. Drupal, Shopify, Joomla, WooCommerce), so the lion's share of all websites, including Facebook or Wikipedia, are developed with different types of PHP frameworks.
As for tech features, PHP is synchronous with multi-threaded blocking I/O (input/output) processing. PHP code is executed on the server-side by interpreters, such as Zend Engine working with Apache or Nginx servers. According to this model, the client-side waits until it gets the results of a script being executed, without having access to the original code, and no code lines are executed until the previous result is received. PHP code can be integrated into HTML or HTML5 markup, which makes PHP very flexible. The language efficiently connects to the SQL database, such as MySQL, MariaDB, or PostgreSQL.
Additionally to asynchronous, non-blocking I/O, Node.js features event-driven workflow and powerful built-in libraries, which make it possible to set interactive client/server communications sessions via WebSockets. The Node.js logic supports micro-services, event queues, and jobs. Unlike PHP, Node.js sends the task to the computer's file system and is immediately ready to process the next request without waiting for previous results to return -- it makes it faster since the waiting downtime is excluded from the operation.
When a discussion starts, some backend developers may name a dozen factors contributing to why they opted for PHP over Node.js: for example, because it’s easier to code and operate and comes with a large and experienced community, so they can find a ready and relatable solution for even very specific situations. At the same time, Node.js is considered to be more powerful with a wider range of applications and faster performance.
Below you may see how they compare in detail.
What about the ease and speed of coding? For many developers, coding in PHP is a faster option because it’s easier to use. A skillful PHP developer can code in PHP with a significantly higher speed rate if compared to Node.js, as there is no need to utilize compilers or converters. The language allows establishing a simple connection to the SQL database without hosting confinements. At the same time, there is a trade-off: PHP programs do not perform that swiftly.
As for Node.js, deployment of applications and frameworks appears a more sophisticated task; nevertheless, a code written under Node.js environment executes rapidly and smoothly since it keeps the server workloads low. With Node.js, it’s possible to maintain a two-way connection website with free data exchange and to get access to the callbacks, which helps you save time when dealing with multiple different threads.
Conclusion: Coding in PHP can be a good thing when you need a quick solution. But if you need a more efficient, complex, and sustainable output, you should opt for Node.js and invest more time in writing and compiling your code.
As mentioned above, these technologies adhere to different concepts in handling requests: PHP has a slower, synchronous code execution procedure, which means that every module or function is processed in the code-specified order. If one query is not executed, the next one will not get executed until the previous one is accomplished.
The process of opening a file in PHP looks like this:
Owing to the powers of the V8 engine, real-time server interaction, and asynchronous execution (order-independent execution), Node.js can boast superior performance and obviously outperforms PHP.
This is how Node.js concurrently handles a file request:
Conclusion: Is Node.js faster than PHP? Because of a slower loading process rendered by PHP, Node.js is the winner in terms of performance and code execution speed. It eliminates the waiting downtime and provides real-time data in a much more efficient manner, which allows using Node.js for high-load projects.
PHP can be combined with HTML; and therefore, it is an integral part of many content management engines such as WordPress or Drupal, making the development process easier and cheaper.
You can also extend PHP with LAMP stack technology and server software, such as MySQL, PostgreSQL, mSQL, MS-SQL, SQLite, PostgreSQL, and non-relational databases like ElasticSearch, Redis, and MongoDB. Besides that, PHP can work together with countless extensions and libraries. It requires the use of package managers, such as PEAR, a structured library of open-source PHP programs, making the scripts/commands accessible from anywhere on the command-line, and Composer, a PHP dependency management tool.
PHP is a pure backend programming language, so its application area is pretty limited. Technically, it belongs to the LAMP stack, which stands for Linux, Apache, MySQL, and PHP/Perl/Python. So to design, build, test, and maintain a completely functional web project, a software developer should be proficient enough in approaching and configuring different systems, along with using HTML and CSS (or you have to hire a team of different engineers to cover all the mentioned areas). Of course, potential dealing with different systems seriously complicates the learning curve. Despite the said issues, PHP is on the track of dynamically developing, with its developers regularly coming up with new stuff and ideas for improving its features and functionality.
Conclusion: Many experienced developers would call it a draw. The powerful package management system (NPM) gives Node.js extra functionality points, but aside from that functionalities are rather similar.
Conclusion: PHP is much more popular than Node.js.
PHP has been on the market since 1994. It has already gained a very strong community and offers an endless portfolio of projects. PHP comes with a huge codebase: 1M+ questions on StackOverflow alone and tons of training material available; not to mention a vast repository of efficient PHP-driven solutions, such as WordPress and frameworks making it easy to develop with PHP. Such a superior richness of the PHP-related resources allows you to cut down development time/costs, and increase the productivity of your team.
Conclusion: PHP looks like a mighty Goliath, while Node.js is an ambitious David. The battle is not yet finished!
There is a large pool of backend devs familiar with Node.js: more than 50% of all developers have had a positive experience with it in 2020, highlighting it as the most popular web development technology. In the U.S., developers skilled in Node.js can earn somewhat between $70K and $100K annually. At the same time, the yearly wage of their colleagues in Europe can fall anywhere within the range of $25-95K (the lower rates are peculiar to Eastern Europe and Balkan countries, which are the top destinations for outsourcing).
The USA-based PHP developers can be hired for an annual compensation ranging from $55-101K USD, with $80K+ on average. These rates are a bit lower in Asia or Europe, especially in Eastern Europe, including Ukraine, Romania, and Russia. As we mentioned above, PHP is a part of the LAMP stack, so you may consider hiring a full-stack developer: their salaries can reach as high as $150K, or about $96K on average in the USA.
Conclusion: Most likely, if you’re looking for either PHP or Node.js engineers, you won’t face a deficit of talent proposition, but make sure that your budget is capable of winning a specialist through the salary bidding.
Conclusion: A real price of a project massively depends on your business needs, the volume of code that is to be written to satisfy them, and the time the qualified developers would have to spend working on your project. Since there are a lot of ready-made solutions available out there, you may get your project done relatively quickly and at an affordable price, especially if you don’t hire developers yourself but look for development outsourcing.
Since PHP is designed as a fully backend-focused language, it can be well integrated with HTML, centralized servers, and databases, and will be the best choice for LAMP stack projects including Linux, Apache, and MySQL. PHP is certainly the right instrument when you're dealing with a CMS like WordPress, Joomla, etc. (with these systems, you can set your web project up in a very short time.) For example, it makes sense to opt for PHP if you’re going to start an e-commerce marketplace, email marketing platforms, content-based websites, personal or business blogs. Some of the most popular PHP projects: Wikipedia, Yahoo, MailChimp, Flickr, and Tumblr — demonstrate the tremendous results that can be achieved with a combination of a centralized server and the use of PHP.
Node.js is exceptionally good for building dynamic single-page apps that work in a data-intensive, real-time manner, including distributed sessions across multiple devices: instant messengers (Slack), streaming services (Netflix), fintech apps (PayPal), online education (Coursera), social networks (Twitter), gaming apps, live chats, project management tools (Asana, Trello), data-intensive IoT devices and applications, etc.
If you’re interested to get a deeper review of how both technologies perform, you may find different technical PHP vs. Node.js benchmarks on the web. There is more comparison of Node.js against alternatives, and below you may find a detailed comparison table of PHP/Node.js features:
Developing a multi-functional website with either PHP or Node.js requires skilled backend developers and project managers. At the same time, simple projects can be completed by a single person in little or no time (for example, starting a personal blog in WordPress or Wix). Please note that sometimes PHP and Node.js are not the only available or recommended development options.
