PHP versus Node.JS

The world of web development is changing rapidly. Every day new frameworks and tools appear on the market. However, there are two open source backend technologies that are very popular for server-side scripting: PHP and Node.js.

What is PHP?

Created in 1984, PHP (Hypertext Preprocessor) is an efficient scripting language that allows users to create integrated web applications. Along with server-side scripting, it can also be used as a general-purpose programming language to create server-executable web services based on MVC architecture.

PHP can be easily embedded into HTML. It is an open source language that supports network protocols such as HTTP, HTTP Basic, and FTP. It is one of the most commonly used scripting languages ​​in the world and works with major operating systems such as Linux, Windows and macOS.

Advantages/Pros of PHP

#1 Very easy to learn

PHP is very easy to learn and can be easily integrated into HTML or HTML5 code. It is an open source framework and has a very smooth learning curve.

PHP has a simple syntax and is very flexible. Additionally, there are many tutorials online that beginners can use to code basic applications. Lastly, the PHP library and frameworks are extensive and cover a lot of functionality. Many PHP development companies use them to develop dynamic web applications.

Huge online community

PHP has a large online community that answers questions and solves simple problems for programmers. They also share ideas and bug fixes, which will be released in future versions. Because of this, PHP has remained quite stable over the last few years.

#2 Speed

PHP applications have a fast loading rate. They can also be loaded with slow internet connections . This improves the site's UX and SEO.

You can also use caching systems like APC or OPcache to increase your speed even further.

#3 Platforms

PHP applications are platform independent and can run on different platforms such as Linux, Windows, and macOS. They are also compatible with cloud service solutions such as AWS.

#4 Database integration

PHP applications can connect to several different databases such as Oracle, MS SQL Server, MySQL and PostgreSQL.

Disadvantages of PHP

Although PHP is an amazing scripting language, it also has some cons. Let's take a look at them.

#1 Insecure

Although the PHP community releases patches and fixes for security vulnerabilities, this open source framework has been considered inherently insecure in the past due to its low barrier to entry and default settings. Your ASCII text files are also readily available to other users.

#2 Performance issues

Using various PHP features can cause performance issues in web applications. This problem is often observed when PHP-based applications handle large amounts of data or traffic.

Additionally, incorrect code integration techniques and coding layouts can also cause performance issues in PHP-based applications.

#3 Debugging

PHP doesn't have many debugging options, making it difficult to find and fix errors in the code.

#4 Essential behaviors

It's difficult to modify core behavior in PHP. To do this, users need to rewrite the application's core components and recompile them.

Which companies use PHP?

As mentioned above, PHP is a very popular language used by industries across the world. For example, social networking sites like Facebook, Yahoo, and Tumblr use it as their backend. PHP is also used by messaging apps like Slack and Tagged.

A number of other companies, such as Etsy, Wikipedia, iStock, Baidu, and Mailchimp, also use PHP for server-side scripting.

What tools integrate with PHP?

There are many tools that PHP developers use to simplify development and increase flexibility. Let's take a look at some of them.

1. PHP_CodeSniffer

PHP_CodeSniffer is an amazing style checker that checks for issues like missed indentation, incorrect naming convention, and comment mismatch. It checks available code against a set of predefined rules for abnormalities and reports these changes as PHP style violations.

2. PEAR

PEAR is a framework and coding framework for PHP. Improves distribution of reusable PHP components. This framework can be installed via the PEAR package manager.

3. Zend

Zend is a popular IDE for PHP development. It has many options for code editing, profiling and debugging. It also allows users to search and index PHP code snippets.

4. Cloud 9

This is a cloud-based IDE for PHP development. Its pre-configured development environment has many options for collaborative coding/pair programming. Users can also use it to track entries in real time.

What is Node.js?

Node.js is a command-line, JavaScript-based runtime environment that allows developers to build scalable applications. This framework allows developers to create real-time applications for platforms such as Linux and Windows.

Node.js uses an event-driven I/O model to handle large amounts of data. Its integrated functions are non-blocking, that is, they are asynchronous to each other.

This open-source framework works on the Google V8 JavaScript engine and uses single-threaded programming. It can generate dynamic pages and allow developers to run JavaScript on the server.

Node.js has a very active online community that provides the necessary dependencies and generators for its users. Node.js development companies need to install Node Package Manager (NPM) along with other tools such as Visual Studio and database connectors.

Advantages of Node.js

Node.js has many advantages.

#1 Asynchronous request processing

Node.js runs JavaScript in a single thread, which allows it to complete requests without blocking. It also uses a fast V8 engine to handle requests simultaneously. This allows Node.js applications to be highly performant.

Node.js also uses caching to improve performance and reduce code re-execution.

#2 Microservices

Node.js is a lightweight technology that makes it ideal for running microservices. Microservices applications are highly flexible as each component can run and modify independently of one another.

#3 Rich ecosystem

Node.js has a very rich ecosystem with more than 1 million packages that can be installed through NPM. It also offers community support and extensive documentation for novice developers. Furthermore, its learning curve is very smooth.

#4 Full-stack development

Since Node.js uses JavaScript for both the server and the client, you can use it for both front-end and back-end development. In this sense, Node.js has the potential to be a full-stack development framework.

#5 Extensible using JSON

Node.js applications can use JSON to exchange data between the client and the server. You can also use its built-in API to create applications with different communication protocols such as HTTP, DNS, and TCP.

Disadvantages of Node.js

Although Node.js is an extensible and flexible development framework with many pros, it also has some cons.

#1 Debugging

Ask any experienced JavaScript developer and they will tell you that debugging JavaScript code is difficult. If you are working on a Node.js application, you will feel the need to integrate your application with testing frameworks to make debugging easier.

#2 Callback Hell

Due to its asynchronous nature, there is a callback in the application whenever a task is completed. Sometimes callbacks can be nested with other callbacks, which can lead to a situation called callback hell. This has an adverse effect on performance and can cause memory issues.

#3 Code maintenance

Programming models with asynchronous models can be more difficult to maintain than linear blocking I/O models.

Which companies use Node.js?

Node.js is a versatile environment used by different companies around the world. It is used by financial companies such as Paypal and Citibank. Ecommerce platforms like eBay and Walmart also use it as a backend.

This framework is also used by other organizations such as Linkedin, Twitter, NASA, Trello, Mozilla and Uber.

What tools integrate with Node.js?

Web Package #1

This is a module wrapper used by Node.js developers to simplify frontend development. This tool reduces application loading time by running multiple packages at the same time. This allows assets to be executed asynchronously at runtime.

#2 Electrodo.io

Walmart Labs tool allows users to develop Node.js applications in a structured way. It can be installed via NPM and allows developers to build complex features from the core code.

#3 Babel

This is a JavaScript compiler that allows users to compile ECMA scripts.

#4 Socket.io

Socket.io is a framework for establishing real-time two-way communication. This communication is event-based and includes additional features such as analytics, counters, and graphs.

Node.js x PHP: main differences

Let's look at the specific properties of both structures and see how they differ from each other.

Performance #1

The Node.js V8 engine and its asynchronous nature allow you to quickly execute code and execute features in the UI. It is also non-blocking in nature, which allows tasks to run concurrently, meaning new requests are not blocked while the oldest one is executed.

PHP is inherently slower than Node.js in terms of performance due to its synchronous nature. This means that new requests have to wait for old ones to fully complete before they can be executed. This slows down the task execution speed.

#2 Development

Developers working on PHP applications also require extensive knowledge of other technologies such as LAMP stack (Linux, Apache, MySQL and PHP) and frontend technologies (HTML and CSS).

On the other hand, since JavaScript is a client-side and server-side scripting language, you can use Node.js to create the front and back end of the application. This simplifies the development process and reduces production slowdowns.

#3 Database

Both PHP and Node.js can be connected to a number of databases for development. However, with PHP, NoSQL and non-relational database integration are not very popular as they can be slow and complicated. On the other hand, Node.js works perfectly with NoSQL and non-relational databases.

Furthermore, PHP cannot integrate graph databases. However, Node.js can work with graph-based databases.

#4 Request handling

As mentioned above. PHP only processes one request at a time. This means that applications developed in PHP consume a lot of CPU and require more resources.

Node.js is asynchronous, which means it can process multiple processes at a single time. This also means that applications use less CPU and RAM time to run.

#5 Accommodation

PHP is one of the most used server-side languages ​​in the world. The vast majority of websites hosted on the internet use PHP. It is compatible with all major hosting providers and can be hosted from anywhere due to its LAMP stack.

Node.js also has hosting options available such as Joyent, Nodejitsu, and Heroku. But they are limited compared to PHP.

6# Installing the package

With PHP, developers need to add and install individual packages. However, with Node.js you can use NPM to install packages directly.

PHP versus NodeJS

What will the future be like?

It is impossible to choose a framework without recognizing the full extent of its current and future functionalities.

The latest version of PHP is called 8.2.0 and was released in December 2021. In this version, issues with request methods and environment variables have been fixed.

The community also fixed bugs related to null pointer exceptions, coalescing triggers, and multiline function calls. The next version name is 8.3, which will have fixes for date/time exceptions, trait constants, and enum lookup properties.

The latest version of Node.js is called Node.js 18, released in October 2022. This version contains updates to ECMA scripting and DNS resolution. It also supports JSON assertions and leverages prefix-only core modules.

The next release of Node.js is Node.js 19, scheduled for release in April 2023. It will have features like the Watch node and the true KeepAlive standard.

Node.js vs PHP: who wins?

As mentioned above, it is not feasible to claim that one technology is better than another before understanding the use cases. Both PHP and Node.js are advanced frameworks that have huge community support and a variety of cool features. However, a decision regarding the scripting language must be made to meet your business requirements.

You must use Node.js if you want to create an efficient web application that is capable of handling multiple callbacks between the server and the client. Furthermore, if you want your application to focus on performance and use real-time data, Node.js is the right choice.

PHP should be used when there are no frequent callback requirements and the architecture is simple. If your server is centralized and you don't need to scale them, PHP is the best option.
